I know people from the East coast have been complaining about Covad, but not everyone has had bad experiences with them. In fact, when PacHell screwed up my Covad DSL line for no discernable reason, both Covad and my ISP were great. I haven't logged uptime percents, but it seems pretty good but not perfect -- much, much better than z.iwethey.org's cable modem.
