Bit of a billing info snafu for this one. Other ones may have been related to softlayer's network itself or the not-so-great server we're living on.
Anyway, that's sorted and we're back up and running.
If you want to have alternative means of finding out what's going on, I've gone ahead and set up a twitter account (
https://twitter.com/gotwootstatus ). If you're having problems, hit that up with a direct message and if nothing else I should get an email about it and be able to reply.
As far as other contingencies go, I own the gotwoot.org domain, and also have control of reddit.com/r/gotwoot. I haven't done anything with either of them ... they're both just things I'm holding onto as contingency plans for now.
I've also got backups (weeklies) of the forum database and filesystem contents, so if it came to it I'd just have to grab some hosting space and restore.
