Tabulas was down last night; the server that Tabulas' database is located on got hacked (not through Tabulas, but through another account that was on the server).
I've written a a more technical post on my personal Tabulas.
I'm *really* sorry about this downtime - I hate downtime with a passion, and I was really stressed out last night while trying to get the service back up. Right now, I'm exhausted, but I will be doing a post-mortem examination of how I can prevent this type of outage in the future.
Again, my apologies.
Note the service may be slightly slow while I reconfigure the server to be a bit faster. Let me know if you're having any critical errors (like database errors and such).
Thanks for your understanding.
