Comcast and Xbox Live 11/9/13

Anyone know what the deal is with Comcast subscribers not being able to connect to Xbox Live? I was connected fine last night, and I get back from work today and want to play some video games to unwind, and cannot connect no matter what I try... Anyone else having this issue?

Tons of Comcast customers are having this issue including myself, and no one seems to have an idea of what's going on. The assumption is that Xbox Live/ Comcast is updating their service and it's causing compatibility issues. Just google "Xbox not connecting to Xbox Live" and a major thread on the xbox forums shows up. I say we just keep posting everywhere (here, ign, xbox forums) until we get some sort of answer about what's going on.
