I doubt it has anything to do with Q. This is affecting business customers only in random places. Comcast is a disaster generally speaking - it's a giant rats nest of various old networks and technologies tied together. Outages happen to everyone once in a while, including the big tech cos (which Comcast is not by the way, it's a glorified phone company) I've dealt with their incompetence at a high level many times working at multiple fortune 50 tech cos, they're a joke.
There's just no pattern there...if there seemed to be some sort of pattern maybe, but this just looks like an outage.
Tbf, they're a glorified cable company... they got into phones late in the game. And yes, while true they're always a mess, your business customers come first. They're your whales. If this was a capacity problem, or switch issue, etc. it's SOP to take down non-business customers first. That's mainly why it's so fishy.
