AT&T residential "Elite" DSL. Adequate for my needs (I don't download mega files), but...eeeuw.
I had Time Warner cable for several years, and finally ditched 'em just before the Comcast takeover was announced. With Time Warner, I averaged an outage of at least an hour almost every month. Gave up on that. The DSL is slower, but I haven't had to place a single outage call to 'em since I've had the service.
