I'm on Comcast and cannot get to Twitter and a few other places... But Netflix and YouTube work just fine. I wonder why I can get to some stuff but not others...
Seeing talks about 2 separate fiber cuts... Lots of issues all over the US. Chicago to NY and also another cut that goes south to SC. r/sysadmin has good info
