For what it's worth, I've had Comcast residential for over 3 years now and have only suffered a severe outage once, but usually no issues like that.

Occasionally at night there are disconnections.

But the customer service is definitely awful. I find I have best success immediately asking to be transferred to the customer loyalty office rather than the call center.

Right, that's the advantage to Comcast Business. It only costs a bit more, and when something does go wrong, you get faster, better-informed service from more knowledgeable people.
