Let's say this happens again the next month (30 day billing cycle); or two months later, doesn't make a difference. Then you've activated your second courtesy month. 12 months after you activated your first courtesy month, you will once again have 1 courtesy month available (I believe, otherwise it may refer to fiscal months, which generally cycles between the 21st and 22nd of each month). The same follows with the second month.

The 12-month period begins at your first overage. It's also worth knowing that if you've used your two courtesy months and go over a third time, you lose your courtesy months permanently, they won't reset after 12 months. 

---

I'm not certain if that's true, but I'm open to some kind of documentation to that effect. I'm not 100% on it, so I could be mistaken.

[Kicken]

What will happen if I use more than a terabyte in a month?

If you use more than a terabyte two times or less in a 12-month period, your courtesy month balance will reset to two at the end of these 12 months. However, if you use more than a terabyte three times in a 12-month period, no more courtesy months will be given. The 12-month period begins the first time you exceed a terabyte.

That seems to be what https://www.xfinity.com/support/internet/data-usage-exceed-usage/ says as well:

... the first two months you exceed a terabyte you will not be charged for overages, no matter how much you use during those months. ...

Hi all! It's me again! Hit the 1TB Cap again just doing normal 'human' things with the technology that we've unlocked as a Race! My family has once again been labeled "Abusers" and become "Heavy Users" of the Internet! When in reality we're just a normal bunch of people that use the Internet for what it's been invented to do! Here's Comcast now with its greedy little pig-face to swindle more money from hard-working American Families! 

Comcast. I have a question. Before you applied a 1TB Data Cap to my account, I had unlimited Data... for years! Correct? Yes. I did. That's the answer, and there's no other answer. So now here you are, taking away that Unlimited Data that I had but you aren't reducing the price I pay every month for no longer having Unlimited Data. Why is that? Greed. That's the answer. You took away a service that I use to be paying for, and you didn't reduce the cost at which I'm paying for that service for no longer having it. Instead, you're now providing me less service for the same price and illegally price gouging me to pay MORE for the same thing I already had. 

Your "Unlimited Data Plan" is an extra $50 correct? Yes. That's the only answer. 

Therefore, my account should be reduced by $50 a month because I'm not longer on an Unlimited Plan; correct? Yes. That's the only answer. 

Explain how this is not how things are happening right now after introducing an Unlimited Data Plan? Which, by the way, has no merit for existing other than to swindle more money out of your Customers.

Hello

Recently I became an xfinity member with a 100mbps internet package. After my first month I was notified that I had gone over my 1tb data cap. I actually exceeded to 1200 gb in one month. I have honestly no idea how my family and I could have reached these levels. We have multiple consoles and laptops connected to the internet, as well as 5 smartphones, however when looking at their data usage for the month, it all totals to around 550gb. I have no idea what else could be causing the issue, I looked to my routers settings to see if anything was connected and nothing was out of the ordinary. Does anyone have any ideas as to what could be causing it?

[Dangrubbs]

That's a lot of devices pulling data, can see how you would bump up against the cap. There is a excellent (but long) thread on the cap, what counts as usage, ways to monitor etc here ( http://forums.xfinity.com/t5/Your-Home-Network/Terabyte-Internet-Data-Usage/td-p/2741624) In short, the only data usage that counts is what Comcast reports and the definition of usage, as far as I know, remains a mystery. You can view what Comcast reports as usage at https://www.xfinity.com/manage-my-account, create a sign in if you don't have one and log in. Go to the devices tab and scoll down to see your current month and the last three months usage.

[jcfish23]

my meter has been stuck at 45GB for the past 2 days and in that time i downloaded around 7GB of files and it has not moved.can somebody please check this out.thanks.

[AWBolden]

Interesting. 3 years later the cap is 1024 gb. Ive gone over 3 times in 9 months. I have used this service before it was owned by comcast (att broadband). I had no problems (except the escalating prices/fees) for the first 15 years until October 2016. Looking elsewhere.

[AWBolden]

We are in a new month.

I Have comcast Blast!  (since 10/2016) usiing ann Arris 862 on bridge for phone, and netgear c3700-100nas as router. I previously used Performance plan.

I have used comcast before it was acquired from ATT broadband.

Last month my service metered at 1031 gb used, 7 gb over limit.

In the first 9 days, my network metered 436 gb. i shut my services down. Technician came out to do some outside wiring. Started up the service again using Netgear as router,Arris as bridge.

Network reached 50% (512 gb) by 6/19, 60% by 6/23, 70% by 6/24, 80% by 6/26 and 90% by 6/28. Shut diwn tge service until 9:00 pm 6/29. My total usafe was 949 at the tine restarted myvservice. At 6:00 am my throughput was 1031 gb. I shut down service again.

Starred this morning 2:00 7/1/17. Checked usage then shut down at 4:00 am. Checked service again at 10:00 am. Service used 40 gb in 8 hrs. No hosts connected. No wireless allowed. Only modem and router connected. Modem is only connected to cable. No connection to the internal network.

Problems. Trying to resolve

update:

User of cable internet since service was owned by ATT Broadband (acquired in 2001)

Turned on my modem and router at the beginning of new month 2:00 am. 0 gb usage. Disconnected from network. No hosts allowed. All wireless devices blocked. Checked again at 10 am. Already used 40 gb.

On what?  Disconnected modem and router again.

Total throughput history since converting to Blast!:

1031 gb in jun 2017.

I have:

no movie streaming,

no netflix ,

no dvr,

but network metered 2x  the total Apr 2017 usage in 8 hrs today.

There is a problem. Comcast needs people who can assist with this intrusion issue.

the usage is not updated that quickly but is done on a schedule throughout the day. go to the web site https://customer.xfinity.com/#/devices and scroll to bottom to get usage. They just changed the 'meter' page so I am not positive we can see usage by the apps on Set top boxes (like Netflix or Watchable) individually. I'm running an hour of Watchable now to get some usage on one of my set top boxes now so I can see if the new usage pays breaks out usage by set top boxes too.

[AWBolden]

Thanks. That's where I got my numbers. Not sure when they update. I was at 0 usage at 2:00 am and had burned 40gb in 8 hrs 10:00 with only the router and modem connected. No devices were allowed. Seeing that I used 19gb for the entire month of April 2017, something is really unbalanced, in my opinion. And I've been a Customer before Comcast acquired art broadband in 2001. I've never experienced cast differences such as these. But thank you for the link. I check it every day.

By the way: we are in a new month July 2017. So my usage for July in 40gb. I'm not sure Comcast would roll June's activity into July.

... processing introduces an overall time lag that causes the meter to update about three hours after the subscriber traffic passed over the network. The Comcast goal is to have the meter update no later than 24 hours after the traffic event.

You may not have waited long enough.

[Paraniod]

Also, from Bruce's link there's a paragraph about the meter changes at UTC time midnight, not local time midnight. Just something else to keep in mind.

[AWBolden]

Thank you.

[AWBolden]

Thank you. Understanding of this policy helps.  

Again, I didn't have these issues for the 15 years before converting to Blast!

[AWBolden]

Strange.  I had my equipment shut down for 12 hrs and disconnected. The system registered 0 usage.  I connect it at 2:00 to 10:00 and it registers 40 GB.

Not sure where the delay is. Thanks for your help anyway.

well it never 'showed' (like the old meter page) the xg1 app usage I ran up on purpose, although they could have just included the usage in the modem 'usage' as if the modem used was the modem.

After disconnecting the Arris - which is in bridge mode, connected by cable, and is not connected to the internal network, my Netgear received this DoS attack through my HP network printer.

if you go here and scroll to near the bottom, someone resolved that the HP printer (that supports IPV6 was confusing fields of some addresses causing that 'attack'. Could it be similar to your situation?

[AWBolden]

Thank you. This helps.  

After removing the iPad and iPhone from my network (they also use IP6) and shutting down the Arris modem, I have used 1 GB in 5 hours (I know there is a delay, but this is 7 hours usage vs 40 GB in 8 hours on 7/1/17. I'm going to remove IP6 from the Arris and both IPad/iPhone devices. I'll check back tomorrow.   AWB

Thank you to Rustyben, BruceW, and Paranoid.

I found out by following the link Rustyben provided. I was in the middle of a perfect storm:

1. Netgear C3700-100NAS

2. IP6

3. iOS devices

The link was to a Netgear forum. Numerous users had issues with their Netgear routers and IP6.  When it appears that IP6 was not being handled properly by the router, the IP address generated a DoS attack.  This was not really an attack, but detected as one.  And the "attack" came from iOS devices which have IP6 running (and cannot be disabled).

All said and done, I concluded why my throughput had metered so high (96 GB in first 2 days of the month, 1GB since then ). Let's say the iOS device attempts to fetch a site on the Internet.  The router sees an external address.  Well, outbound it doesn't care that the address seems to be external (65.0.80.31 actually is pulled from the actual IP6 address 128 bits). But the inbound traffic from the fetch is trying to return to the device.  Well needless to say, the fetch is completed under IP4 (32 bits), but continues to hammer away attempting to return the website to the device and finally times out.  Now what happens if every fetch to the internet from these devices bangs away at the router until it finally times out.  My usage increases to astronomical proportions. I removed the IP6 from my Windows 7 devices and also fixed the DNS in the router to the assigned DNS (IP6 won't show).  

Thank you again.   Comcast support asked me if I needed to purchase an unlimited plan.  With the Comcast forum, I have the assistance I needed.

I am very frustrated with Comcasts Data Cap,Its causing me a lot of stress and worry each month .I cant afford to pay for unlimited nor pay extra if we go over.My family doesnt understand the data issue,and I am just tired of being the internet police.We have up to 8 computers /and TVs running at any given time,Yes I have a big Family(5 bedrooms ,8 people in household.)My question is ,is there anyway to set the Internet on say max  GB use of 30 GBs a day and shut off internet until following day.This seems to be only way my household will get the point.Any help would really help me out..Thank You

What brand and model router do you have. I’m only aware of Netgear routers having this feature but I could be wrong. I’m not sure if other router manufacturers have it.

Would you be able to say this issue is only for your Netgear router?  I don't have a Netgear router; I have a Comcast gateway.

[AWBolden]

Well, my intrusion issue is solved. I belived the issue is more of an ip6 issue. I am still having gb overusage. But my claim that the comcast network was being intruded was technically solved, due to the ip6 issues on the devices. Still working.

Since my ip6 issue was highlighted on the netgear, i have been trying to get inside of the arris gateway relieve it from ip6. So far, i havent been able to log in with the dedault user id and password. Ive reset it multiple times. Usage since last night is 58gb ( from 97gb) for a total of 155 gb for the month. Still high (avg 38gb per day). Better than 40 gb in 8 hrs.

[Rustyben]

From what I've read in the past, Comcast's network that your modem connects to is pure greenfield IPV6 and the router manages the sending of IPV4 only traffic over the IPV6 network. Note that your windows machine may be set by default to obfuscate your actual IP (feature of IPV6) by 'using' a differnt ipv6 address within the allocated number range of the network that if 'attacked' won't go back to your actual IP. (pretty cool). Point of that is that the router should have a setting to change to IPV4 only (for devices on your network).

my netgear nighthawk is set to IPV6 and tests at http://test-ipv6.com/ with score of 10/10 for ipv6. my usage with a lot of streaming runs under 500 GB per month.

Cite? I have never seen or heard an authoritative source say that Comcast's network is "pure IPv6". Even if true internally, it hardly matters to users and to other networks, as Comcast accepts and delivers both IPv4 and IPv6 traffic to and from its customers and the systems they connect to.

[asdfdasfwerwr]

This stupid comcast data usage meter says I overused 200GB last month. I've never even used more than 500GB before. And this month (July) it says I used 70GB as of 7/3. 70GB, in 3 days, from 7/1 to 7/3, when I was on vacation and nobody was home using my Internet! And today, I even completed disconnected my modem for 2 hours, yet it still shows 13GB was used during the period.

I called them, chatted with them online, messaged them on twitter, and they were extremely unhelpful. All they say was "virus scan", "change wifi password". I did scan, no virus was found. I changed my wifi password, but there was nobody ever stealing my wifi - I could recognize every connected device. The customer service doesn't care about its customers, all it cares is our money. They tried to make me pay extra $50 to get unlimited data. No, I'm not going to pay you extra $. If you don't care about us and our problems, we can find someone else who cares.

Interesting reading here about the ip6 issue, I noticed that when i try to use the xfinity speed test page, it shows my ip6 speed at 0 - 10 Mbps and I need to switch the test to ip4 in order to see the 150 Mbps. I don't know if this somehow relates just an observation I made. Support was not informed about the difference when I called and asked.

were you using this site? http://speedtest.xfinity.com/ There is advanced settings menu to change to IPV4/IPV6 for the test.

Seems that they did that already ??

Hello, asdfdasfwerwr. I have sent you a private message with our Customer Security Assurance team's contact information. Please contact them for assistance with data usage disputes and inquiries. Thank you.

[jsnedwrds]

Fiber almost here OMG I cant Wait!!!!!   After 20 years of being with comcast they finally found a way to get me to stop paying them!

[Pinkpoppy]

Starting March 2017 my usage spiked DRAMATICALLY, prompting notifications about usage and going over the limit. I'm in a 2-person household, do not work out of the home, do not play games, and streaming is very normal and limited. Our normal consumption is between 170-350 Gb per month. But every other month since March the data starts spiking at some point mid-month, to an astronomically high number for the rest of the month. And then it magically resets back to normal on the 1st. In May the worst part of the problem started when we were on vacation! I know there wasn't anyone accessing it because I would get an alert if someone was accessing our network. 

When this first happened we double checked the security, changed the passwords, and installed an app to monitor which devices were using the system. There was nothing abnormal about any access. I've spoken with so many reps and people on the security team and I've been told that they have no way of accessing the data usage by device. But they can guarantee there's nothing wrong with their monitoring???  

I have shut off my wifi today and it continues to jump. Every person I speak with acknowledges there's something very wrong, understands why I'm frustrated but says there's NOTHING they can do or suggest that I haven't already done. and of course, the data usage chart only shows by month, not by day or device, which is what I need to be able to solve the problem...since they refuse to solve it for me or credit me the fees that I'm being charged!

This is unacceptable and I'm about to contact investigative reports team from local news to look at this.

Starting March 2017 my usage spiked DRAMATICALLY, prompting notifications about usage and going over the limit. I'm in a 2-person household, do not work out of the home, do not play games, and streaming is very normal and limited. Our normal consumption is between 170-350 Gb per month. But every other month since March the data starts spiking at some point mid-month, to an astronomically high number for the rest of the month. And then it magically resets back to normal on the 1st. In May the worst part of the problem started when we were on vacation! I know there wasn't anyone accessing it because I would get an alert if someone was accessing our network. 

When this first happened we double checked the security, changed the passwords, and installed an app to monitor which devices were using the system. There was nothing abnormal about any access. I've spoken with so many reps and people on the security team and I've been told that they have no way of accessing the data usage by device. But they can guarantee there's nothing wrong with their monitoring???

Shot in the dark (wish I had a real answer); try turning off your public hotspot, if you haven't already.

I Have concluded that my usage problem is internal. I have monitired my usage and it points to activity on my internal network. When my router is disconnected from the LAN but connected to Comcast, no activity was used. After I connected 2 devices, 1 wired, 1 wireless, my network used 58 gb in 5.5 hrs.

My problem could be some within software that exists on both devices.

I Will share future discoveries with the forum.

Is anyone having a problem with captive.apple.com? This could be one of my issues.

I think it is unlikely that Comcast's DNS is causing the issue (the 75.75.75.75) but you could substitute google's DNS to test at 8.8.8.8. re captive.apple.com that appears to be a hardwired part of iOS that allows a local wifi network to 'intercept' any web page to a login screen for the wifi and that 'call' saves the desired page and proceeds to it when login on wifi is complete (often just a checkbox accepting terms and conditions of that wifi network). the local ip 192.168.0.* is probably your printer or some other device that is trying to join the network.

DATA meter missing on my account  have been trying for 3 weeks to solve  no luck with comcast   can they not fix anything?

[TibbieMom]

This week was the first time we've ever received warning notices about our data usage. We're currently 248 GB over the monthly limit. Something is seriously wrong. Our monthy usage this year has been

Jan. 180 GB

Feb. 73 GB

Mar 113 GB

April 92 GB

May 395 GB

Jun 622 GB

Jul 1272 GB (so far this month)

It doesn't take a rocket scientist to see there's a problem. We only have two adults in the home; we don't stream music, we don't play games. I called Comcast yesterday, and I was transferred to SEVEN DIFFERENT PEOPLE, for a total of two hours on one call. The last person I spoke with suggested I change my router login from the default, which I did. I also changed our wi-fi passwords and renamed the wi-fi networks. There were no strange devices showing on the gateway login page. In the past 24 hours, our usage went from 1196 GB to 1272 GB. 

I've read at least half of the 40 pages in this forum thread, and it couldn't be more clear that something is going on. Why aren't we getting any help from Comcast? They should be able to troubleshoot these data overages and solve the issue. We've been with them forever, so they should be able to figure this out. Can't they send someone out to troubleshoot this? One of the people I spoke with yesterday said they didn't have anyone to work on this type of issue. What?? 

Short of switching internet providers, I have no clue where to go from here. Can a Comcast person here please respond and help figure this out?
