Being down only an hour or 2 a year isn't bad.. every host has to do maintenance from time to time, and even at 2 hours a year down time that's a 99.977% uptime, at 1 hour a year it's 99.989% uptime.. either way that's pretty decent. The best you're likely to find is 99.999% uptime at any host, so these numbers are pretty much right on spec.
