I've had excellent service from XO, including helping us get back in business when Northpoint went under. They could have given us more warning about the Northpoint problems, but such is life. They got us a dial-up within a day or two, and re-provisioned a new dsl line in about 10 days using Covad.
I'm just concerned that the financial condition/shock market problems may take them down. Covad is also getting to the same precarious position.
