Everything has not been 'going down' recently. I have very detailed statistics on server reboots, mail performance, mysql performance, etc. Stability and performance have been steadily improving for months now.
The data on the mysql servers is backed up nightly and the live data is stored on a raid 5 disk array. In this case two drives failed at the same time, which meant the raid did not have time to rebuild a parity drive on a spare. Dual drive failure is very rare, but the nightly backups are the safety net for such an occurrence. In this type of case you will lose the data between the last nightly backup and the dual drive failure. Still the system worked as designed.
Any data loss is painful and I have credited your account for one month of service. Our customers have been very clear that they want the best hosting possible that costs about $10 a month. Currently, fully mirrored database machines each with their own raid 5 and hot live backups is not feasible at that price point, but we are always on top of the server component industry prices and are quick to upgrade our plans to reflect the current market.
