smp1 - smp2 - smp3 - smp4 - smp5 - smp6 - utopia

Here are are the notes and disclaimers:

It takes over two hours of downtime for each server to upgrade because it has to convert all of the world files (gigs and gigs worth).
Bukkit (the Minecraft server software) is in a BETA release. It is stable although small bugs will come up, please report them to JustinGuy (click JustinGuy's name and you can private message).
Anyone who finds a bug/glitch and uses it to an unfair advantage (duplicating items) or to circumvent the rules, such as griefing, will be banned with no chance of appeal. The proper thing to do is message me with a report.
Vault will be disabled on upgraded servers until they are all upgraded.
Lag may be normal for a little bit. We have to re generate all of the live map data.
