Are you on Chopin?
This happened to me on Lotus the other day. The databases were rolleb back by about 2 months. It just corrected itself after an hour or so. The link from MySQL to accounts was broken, so the server defaulted back to the latest working one, in my case, 2 months prior.
Hope this helps
Same situation for me. Added new forums, groups, and did all the permissions for each user group, to find that MySQL kicked the bucket the next day, and I had no backup.I really hope so - I spent tons of time on my new blog all this week - I have a backup from the other day, but I am hoping I didn't lose the changes I made on it last night. Can't wait for MySql to come back up.
Yeah, 99% sure.
I think admin must be applying an update, which is causing http and cpanel to go down, then everything to come back online, before they have the chance to rebuild the MySQL links. The exact same symptoms happened on Lotus yesterday (or the day before, can't remember.)
Keep calm, and try not to cry
Edit:
And, DO NOT apply a backup, it could corrupt the database if admin are currently working on them.
