I will forward to my Comcast contacts.

Subject: [outages] Comcast DNS broken?

 

Hi,

 

Comcast DNS servers (75.75.75.75, 75.75.76.76) seem to be down. Web pages were 
suck at dns resolution phase, switching to Google DNS solved the problem 
immediately.

 

Tested from San Francisco.

https://pulse.turbobytes.com/results/556d1b32ecbe4023eb0000ab/ - Using our tool 
we see timeout from Seattle and Mountain View. Is this a national level outage 
or something?
