[outages] Comcast DNS broken?

[Sajal Kayan]

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?
