[outages] Comcast IP routing issues, Western Chicago Suburbs (fed from West Chicago)

[Jeff Martinez]

That I don't know.. I just know my customers in Illinois can now connect
without issue. If there are lingering issues, I'm unaware.

We have one local customer in northwest Iowa, who has another location in
the broader Chicago area that's served by Comcast, that had VPN issues
yesterday.

Has Comcast resolved the issue?

Has anyone seen issues in the western Chicago suburbs on Comcast today? At
~1:50am it looks like there was a brief outage, then a route change within
the comcast network between 350 cermak and West Chicago (according to PTR
data), and all day I've been fielding calls from our VoIP Customers who have
comcast business/Home circuits that all seem to go through West Chicago.
Some Comcast IP's I can ping from my HE/Zayo circuits, others I cannot, yet
some TCP Applications appear to still work to those IP's.  Since the route
change this morning, UDP Traffic has been randomly getting through.  ICMP
Between Comcast IP's within west Chicago appears normal.  The Customers I've
talked to also report sporadic outages/slowness to cloud services.
Attempted to contact Cocmast through the normal support channels, but since
things are 'mostly' 
working, haven't gotten anywhere with Tier1 support yet.

Happy to provide trace routes as needed, but since it's happening across
multiple circuits/IP Blocks didn't want to include random data if it's a
known larger issue.  We did have High winds last night, so it feels like a
fiber is down somewhere, and routing is wonky now.
