Services: Broadband (DSL) internet, POTS, digital satellite TV (through DirectTV), web hosting and related (email, etc).
Region(s) Serviced: San Francisco Bay Area, California, USA.
Decent internet speeds
Excellent customer service
Backup dial-up service for DSL customers (but who has a v.92 modem these days?)
Availability is spotty in their service region
DSL requires a phone line from the region phone company (AT&T, e.g.)
I switched to Sonic.net from AT&T early this year after reading about them on Ars Technica and after several years of being consistently pissed off at the pseudo-monopoly that AT&T exercises in my neighborhood and $50 a month for 3mbps down. My monthly bill hasn't appreciably changed ($52.06 with all taxes and fees) and my download speeds (12-17mbps) approach the advertised maximum for my service plan (20mbps).
Their call center isn't outsourced, and the technician who installed my service was an actual technician who knew what he was doing/talking about. I've never spent more than 5 minutes on hold, and have only had to call them up once anyway. Compare with the 2 hours I spent on the phone/on hold last week dealing with 3 different AT&T account reps in two departments when the modem in my office died.
