Comcast XFINITY → [CCSite] Cannot log into Comcast account

Anyone having issues trying to log into Comcast accounts? I get 404 errors or gateway errors if I try to sign in. This is also affecting the Comcast forums. I tried Firefox, IE, and Edge. Webmail also doesn't work, getting stuck on login.comcast.net. POP mail works with Thunderbird.

No problems for me (yet). Don't know if it's geographical but I'm outside Philly, and I also checked with my work VPN based in the southeast US and was still able to login

I'm in the Chicago area. It's working now.

Yesterday I was at my parent's house, and saw this happen on my mother's computer. When I tried again, it worked. Might be some sort of local glitch.

i'm in central nj.can't login to comcast webmail,it justs redirects back to the homepage,read lots of other people with same issue.windows 10 mail app works and android app also works,only the webmail not working.this started happening to me when i got migrated to the new webmail design.

I'm in central MA, was able to log in earlier today, but just now got a box with message - Connection error - this service is not available right now - retry.. For a while now, this new webmail has been slow loading. Difficult to find answers in the comcast forums with the post count not being cleared.

Can login at comcast.net, but webmail from there fails -- either dumps back to my.xfinity.com or gives a connection error.

Email from a client like Thunderbird fails when trying to "copy to the sent folder" on my IMAP mail account.

Summary: Email R broke today.

Interesting-- Just got this when trying to log on to email --

"503 Service Unavailable
