My Domain/IP Keeps getting blocked BUT ONLY ON XFINITY!
I have my own domain, gr8britton.com, on which I host a webiste, email and OwnCloud for syncing files, contacts and calendar. All works great for awhile. All of a sudden, I will not be able to reach my domain ONLY WHEN ON MY HOME XFINITY Internet. If I use my mobile carrier (TMO), Work (Cox) or even home with a VPN, it works fine. I have spent HOURS on the phone with the ridiculous Xfinity support to no avail. Even have one try to tell me that a pinched coax would cause this. Seriously?!?!
I always get, "we don't block IPs" but Xfinity is the ONLY carrier that keeps doing this. Sometimes, it clears up after a few days, sometimes it is weeks. Unfortunately, I have no other viable Internet options than Xfinity or I would change in a heartbeat.
Performing a traceroute gives me:

I understand the problem is happening when not at an Xfinity device (at least by its name I am assuming) but the path is due to a partnership with Xfinity. (Proven by the fact that this ONLY happens when on Xfinity.)
How do we I get Xfinity to actually look into this?
For now, I'm using a VPN to route differently and that is working. However, I would need to have a VPN for all of my connected devices that need to access my server.

It sounds so much like the VPN issue that I had. I would replace the Comcast modem or factory reset it. Not sure how it works, but it solved my VPN issue twice. Please post back your solutions.

Update: As usual, the offending router eventually quit blocking my IP and it is working....for now. It WILL happen again as it always does.

The trace you posted shows Comcast passing the traffic on to Windstream, which then passes it on to PhoenixNAP/Secured Servers. What happens to your packets two networks beyond Comcast is completely beyond their control.
What changes when you swap out your modem/router gateway or use a VPN is the public IP address, which is what the remote server "sees" as the source of your packets. If the server detects traffic from that IP that it is programed to block, it blocks it. Your trace does not show you being blocked by Comcast, it shows your public IP being (possibly) blocked by a device far downstream from them. I say "possibly" because it is not rare for a trace to fail as yours did, yet actual traffic gets through.
You need to work with the admins of the service hosting "gr8britton.com" to resolve this. Fun though it is to bust on Comcast, this one does not appear to be their fault.
FWIW I can reach the site using my Comcast connection with no problem. My trace looks like this:

Hey late to the thread here but are you referring to here? <I cannot justify resetting my modem/router and having to completely setup the router side again>
Is this reference to firewall rules?

I'm experiencing the exact same issue and I see no solution. It's very frustrating and Xfinity helpdesk is a joke. All they do is ask me restart the modem!
