There is a Backbone device that is/was mis-behaving in Denver that is causing some traffic issues. We're in the process of getting corrected..... -Steve On Tue, Oct 11, 2016 at 3:31 AM, Dave Pascoe via Outages < outages@outages.org> wrote:

There does appear to be some sort of Comcast outage. I have a remote system out there that also went down in the last hour.

Anyone aware of any Comcast outages in the Denver area? Have a number of VoIP clients that are on Comcast circuits around the Denver metro area that are all down right now. I monitor their gateways in Nagios too and they are all 100% down at present. Trying to access them via Cogent and Level3 with the same results - 100% failure.

Thanks.

Chris

I'm seeing Comcast cable modem issues from my house here in Denver. Details from my account portal indicate an ETR of 7AM Denver time Sent from my iPhone On Oct 11, 2016, at 3:01 AM, Dave Pascoe via Outages <outages@outages.org<mailto:outages@outages.org>> wrote: FWIW...seems like Comcast traffic going west from Comcast in the New England area is dying at 350 E Cermak in Chicago. This is also affecting ISPs that get transit from Comcast out here, at least for Comcast destinations west of Chicago. Can't tell if it is limited to only certain Comcast markets out west...but it is definitely affecting Comcast transit in the Bay Area AFAICT.

We have noticed an issue with a single Comcast connection in Michigan (in the SW corner of Michigan) that has been intermittently up/down since Friday. Same story as the rest (goes through Level 3 around Chicago with issues before coming into Michigan). -----Original Message----- From: Outages [mailto:outages-bounces@outages.org] On Behalf Of Jeremy Chadwick via Outages Sent: Tuesday, October 11, 2016 7:34 To: outages@outages.org Subject: Re: [outages] Comcast outages in Denver metro area Issue in question was extremely widespread -- a large portion of the US east coast (from Maine to Florida), as well as Colorado, Washington, Texas, and California; I can confirm the latter. Issue lasted from 00:56 to 04:08 PDT (UTC-0700), according to my periodic mtrs between Mountain View (Silicon Valley) and Seattle. Sadly, my return-path traceroutes (SEA->MV) weren't working during the outage due to a configuration mistake on my part, so I don't have a full picture of what happened. For general end-user complaints, the #comcastoutage hashtag on Twitter has quite a lot. There is strong speculation this was Level 3 botching something -- which, if true, makes 2 major outages in 7 days. -- | Jeremy Chadwick jdc@koitsu.org | | UNIX Systems Administrator http://jdc.koitsu.org/ | | Making life hard for others since 1977.
