JIRA showing 10 months old information only (URGENT)

Something is wrong with JIRA. I can’t access new tickets. It shows me tutorials as if i was new user. On releases page i see only releases 10 months old. Do we have a backup?

This was caused by scheduled maintenance by our hosting provider. Apparently, we had two database instances on the server. After a reboot, the older one started first. The problem is fixed now (and I’ve asked for the old database to be de-installed).

Everything looks fine now. Thanks
