I believe my Internet is being throttled during specific times of the day
Hello,
I am someone who broadcasts on Twitch. And 5 out of the last 6 days, between around 8 PM and 10 PM at night, the upload bitrate of my broadcast tanks, and I start to drop massive amounts of frames.
I'm reluctant to call support for this, because it can be tough to get someone on the phone who even understands what I'm talking about, so I'm hoping an employee here can look in to this.
I can supply graphs in which long broadcasts have no problem at all for many hours, and yet right around this 2-hour window, a problem inevitably occurs.
Edit to add more information:
October 15: Broadcast started at around 5:45, upload tanks and massive frame drop at 7:50
October 16: Broadcast started at around 6, upload tanks and massive frame drop at 7:50
October 17: Broadcast started at around 6, upload tanks and massive frame drop at 9:13
October 18: Broadcast started at around 1:15, and goes for 8 hours with zero frame drops, until 9:15
October 20: Broadcast started at around 6, upload tanks and massive frame drop at 10:13
Here is an imgur album, with this information graphed from Twitch Inspector: https://imgur.com/a/dCihHdS
After the first night, I tried resetting my router and modem. I also lowered my max bitrate from 6000 kbps to 5000 kbps. I tried using different Twitch servers around the NE. Nothing helped.
I am actively broadcasting while this happens, with hours upon hours before it does, and nothing changes about the broadcast. I am playing a video game and streaming it to Twitch. No other people use my internet, and nothing else is consuming my bandwidth at this time to cause such an issue.
2nd Edit:
October 21st: Broadcast started at around 6, upload tanks and massive frame drop at 8:54

Your issue could be numerous things. Cable modem signal problems can sometimes manifest themselves as periodic occurrences that start/stop based on some outdoor physical problem (certain times of the day the temperature/humidity rises/falls to a certain level that triggers noticeable issues). But when the problem is happening, if you aren't noticing any other website or service having problems, then the problem is likely the interconnection between Comcast and Amazon (who owns Twitch). Problems h often happen at points like this because the link between the 2 companies is over-saturated. In that case, there is nothing you can meaningfully do to solve this. You will have to wait until that link is repaired (likely meaning upgraded to a higher capacity, likely meaning money changing hands between the companies). Comcast has a long history of extorting peering partners like this for money. In the past I was told by senior technical Comcast personnel that the "Business" class service has a higher priority, but i have no idea if that would apply in the case of over-saturated peering, and I have no way to verify what that person told me is truly correct.
Good luck!

And I was told by many CC insiders over the years that Residential Class and Business class use exactly the same infrastructure, regional (CRAN) routing, and backbone routing. Who knows...

Greetings, ant24x! Thanks for taking the time out of your day to reach out about your connection. We want that working great all the time and are happy to help! Are your streams dropping all the way during this time or it just lags? Are you wired from a PC to the modem?
