A few hours ago, the primary server hosting our user database had an issue that has resulted in the corruption of our primary client database and the loss of the last 2 months of information from our client database due to a separate issue with our database backup procedure.
No user data has been permanently lost, and as far as we can tell, none of our servers have been compromised. We are still investigating what caused this to occur - at the moment it looks like filesystem corruption on our primary server.
