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.
