@user_d50543​ I'm also a recruiter and totally kneecapped here. I'm taking all my Teams meetings/calendar events  and LinkedIn activity via my phone on mobile data, I have no viable solution for shared documents in onedrive as they're inaccessible. I can still access the ATS/CSW, smartsheets, and outlook though so I'm relatively functional. What a mess Xfinity has created for us.

I find it odd that customer support does not seem to know anything about this issue and wastes our time on calls when I know and have seen the bulletin that has been sent out to field techs.

@d0gg​ tired last week with no luck seems to be an issue with the EPON modems as I have connected just fine on standard coax as well as Xfinitypublic networks and mobile hotspot. Xfinity tech was no help I have multiple tier2 tickets open yet have no updates as to mean time to repair. 

[Edited: "Language"]! =) 

I thought I might have had something!

Have you tried connecting when you are on a VPN?

@d0gg​ Here's what happened when I tried your suggestion on June 21, 2022 at 3:00 PM MDT: (it looked OK when I first posted it but then I made a tiny edit and it all collapsed into the mess you see below)

@d0gg​ On June 21, 2022 at 3:05 PM MDT, I tried a VPN and the problem goes away.  Between not needing a VPN when I'm at local coffee shop vs. needing a VPN to connect while in my house in order to use anything Microsoft-related such as OneDrive, I'm 100% convinced this is yet another example of a conflict between Xfinity and Microsoft.   Go ahead.  Search the internet for the phrase (without quotes) "xfinity onedrive" and you'll see that this mid-June 2022 issue is just a repeat of the same old issue that pops up every few years.  It tells me that whatever relationship Xfinity has with Microsoft becomes "toxic" for reasons I do not know or understand every few years.

Has anyone done [and posted] tracert and a ping for us to see?

@Again Yes, when I was working with an Xfinity Agent over the weekend, they had me run a few tracerts. The output contained many instances of "request timed out". My ticket is still open with no updates since Sunday night. 

@Again​ My tracert, posted in a different thread, shows several "reqeust timed outs" when I'm on my home network.  When I go anywhere else, like a nearby coffee shop, none of the issues that all three of my devices experience at home happen at those external locations.  That tells me this is 100% a problem (that a search of "onedrive" without the quotes shows happens every couple of years) between Xfinity and Microsoft.  I don't know why this identical issue keeps coming up but a few of us would appreciate if somebody would knock a few heads together and get this resolved once and for all.

If you are using an Xfinity gateway, you could try turning off their 'Advanced Security':  https://www.xfinity.com/support/articles/using-xfinity-xfi-advanced-security

There might be a time lag before it goes away.  They say there's a 10 minute time lag when you turn it on.

If you are using a 3rd party gateway, try changing the DNS servers on it.  Try cloudflare DNS (does not track you) at 1.1.1.1, 1.0.0.1 or google (does track you)  8.8.8.8, 8.8.4.4.  I've never had much luck with default Xfinity name servers.  You can't change them on Xfinity's stuff.  See if it works any better.

There seems to be a few other folks that are having problems with Microsoft and onedrive recently here too.  IPV6 might be wrapped around the axle again.  There are some office 365 issues with ipv6 only implementations that don't have ipv4 dynamic fallback  https://docs.microsoft.com/en-us/microsoft-365/enterprise/ipv6-support?view=o365-worldwide . 

There isn't much you can do about it as an end client.  For a temporary test on windows 10, you can try disabling ipv6 just for now: https://windowsloop.com/disable-ipv6/  Perhaps that will help for now.  If it doesn't, turn it back on.

This is a problem with the Comcast EPON Routers/Modems. Issue is known to Comcast/xfinity but i am not sure what they are doing to address the issue.  Has been an issue for a over a week now. Effects all Microsoft accounts Office 365, MSN, LinkedIn, etc.

I would also add that you cannot adjust advanced security settings on their EPON gateways. In addition to that-most complexes with EPON have blocked all other ISP's...so we cannot edit the settings, and we cannot find another provider here.

@user_83dad9​agreed also maybe admitting this is and issue with Xfinity rather than saying it is a blocked site. other sites that may also be having issues are Linkedin.com and any developer.servicenow.com/******* site

@user_5e3c64 Hopefully will get resolved soon. When calling customer service most of them seem to have no idea or understanding this is a known issue and they want to restart your router LOL. I have been told by two field techs that a bulletin has been sent to them regarding this issue.

And yes it is all Microsoft related sites including LinkedIn.com

I have been told that they have engineers working on the issue but have not been given any timeframe for resolution.

@user_83dad9​ EVERYONE: Please ignore the Xfinity usual "scripted remedy" because it will be a waste of your time. 

Please also recognize that their online "chat" support people have no choice but to try the usual "standard playbook" remedies for this issue, so don't get mad at them - just ignore them until Microsoft and Xfinity figure out yet another (because this happens every few years) "truce" in the (apparent) on-going war between the two companies over how Xfinity's MoCA configured modems deal with various Microsoft sites.

I've started moving all my OneDrive files over to a folder in DropBox called OneDrive and will keep them parked over there until this issue is resolved (if ever).  It will take days to complete the migration (over 5200 files remaining as I write this on June 22, 2022) but it's better than not having access to them at all.

Looks like one of many in the past couple days.  If there's a bottleneck on Xfinity upstream from you, about the only thing you can do as an end user, is VPN past it to somewhere else, and exit on someone else's network to microsoft's servers.

You got 3rd party gateway, so no 'advanced security'.   Changing DNS on a 3rd party gateway was a good idea too.  You can try disabling ipv6 for a test:  https://www.itechguides.com/disable-ipv6-windows-10/  (reboot).  Change it back if it doesn't work.  You won't be able to mess with specific protocol parameters on a gateway for debugging, and it won't help if their network is screwed up in the first place. 

Nobody seems to want to report how they fixed it, or if it was fixed after talking to Xfinity, so report back if you find a way.

Thanks for the reply @flatlander3.  As for IPv6, I had it off for a while, which didn't help, but noticed that some Microsoft services actually came back online for me after I re-enabled IPv6.  I would assume that means IPv4 connections to those services are not working (i.e. blocked), but IPv6 connections are not blocked.  It is still intermittent though, so not sure having IPv6 on fixes everything, but appears to help the situation.

It is interesting that we are not hearing much from people on how they fixed it.  I would assume it was after Xfinity support, probably Tier 2/3, got involved and did something to their edge routers/firewalls to stop the blocking of packets going to Microsoft servers.  From a customer's perspective, they probably will never get the full story about something like that, and things will just start working again.  Although I would love to know what it is they are doing to fix it.
