No issue here with my 5 Comcast Business accounts (central Indiana), although 
we are using OpenDNS.  The VPN tunnels are up and running between those sites.  
Friends of mine who live up near Chicago who use Comcast and use the default 
DNS servers from them are reporting they are up and running.

Subject: [outages] Seemingly Nationwide Comcast DNS Outage

Seeing many recent reports on the interwebs regarding a “nationwide Comcast 
outage”.
Looks like it’s an issue with Comcast DNS (75.75.75.75 / 75.75.76.76) and not 
anything else, as queries to other public DNS servers (ex: 1.1.1.1 / 8.8.8.8) 
work just fine over my Comcast service.

For reference, I’m located in Chicago, but I did perform NSLookup’s from a box 
in NYC, Dallas, and Seattle which resulted in similar behavior as seen below.

nslookup google.com 75.75.75.75
Server:  UnKnown
Address:  75.75.75.75
*** UnKnown can't find google.com: Query refused

nslookup google.com 75.75.76.76
Server:  UnKnown
Address:  75.75.76.76
*** UnKnown can't find google.com: Query refused

nslookup google.com 1.1.1.1
Server:  one.one.one.one
Address:  1.1.1.1
