Time Warner outage?

Hey all, anyone else having issues with Time Warner residential or
business connections? One of our offices is down and the route is not
currently in bgp. http://downdetector.com/status/time-warner-cable
shows thousands of reports of outages on the consumer side starting an
hour or so ago so I figure it's a larger issue than just my one office;
couldn't reach anyone by phone.




I have a branch office in Syracuse,NY that appears to be down at the moment
that uses a time warner business connection for internet access.


I've have residential twc in Cleveland. My router has an ip in the 104.139.34/24 network that isn't being advertised via bgp anymore either. I can still trace route out from here half a dozen hops, so seems like an edge/peering issue somewhere.

My whole campus (~10000 users) is down... Since roughly 6am. TWC is our upstream.

Same here. Seems like no traffic is exiting TWC:

Tracing route to ns03.savvis.net []
over a maximum of 30 hops:

BGPMON shows my routes falling off the net at around 5:49am.

We now sit at their mercy....

All of WNY seems to be dead. Craps out what looks like inside TWC, so looks like they lost something big.

Just came back up for me.

Came back for us, too, at about 7am.

Outage was a biggie this time:


Can't wait to see the postmortem report on this one.

I had a CNN breaking news email on my phone about this when I woke up, their backbone apparently was down from 2 ish to 4 ish AM.

TCAM? Those of you with TW, how many routes are they advertising to you
via BGP?


The issue reported on our side was impact to TW from a L3 maintenance that caused the issue. No details beyond that to share unfortunately

I believe this is what is commonly referred to in our industry as a “resume generating event”.

This just keeps getting better and better:

Will be right back...

Thank you for your patience.

Our engineers are working quickly to resolve the issue."

My upstream is Charter Business...

I heard the following,

It was actually an engineer doing maintenance on the dhpc server that
stopped customers from getting an IP address when the connected to the
network between 5:30 and 7:00. The funny part is upper Managment heard
about it on the today show

Something sounds really unlikely about that. Lack of DHCP would not cause reachability problems except for the clients. The trace below looks like a transit connection that should be unaffected by DHCP. Looks more like a routing issue. Also sounds unlikely that one DHCP server would be covering this large a scope.

hehe... We call them 'Character Builder Events'.

    Everyone gets to find out how much pressure they can take, beak new grounds, what they are made off, etc etc.

'Shit Storms' come in waves..... typically these are not caused by singular events, but more like a 'Series of Unfortunate Events'.

We don't wish this on any carrier, but sooner or later everyone has to go thru it.

I have never seen BGP drop peers because of a DHCP failure.

I would love to see the breakdown on that.

TW NOC had said it was a Level 3 fiber maintenance gone bad that took down their peering connections when we called in at the time of the event.

Can anyone confirm one way or the other?

Sounds more likely than "we broke the dhcp server".
