Power failure

One of our UPS started to behave. Instead of providing continuous power, it started to turn itself off for a few seconds and back on. This caused outage to the main web server which had to re-sync the hard drives. It happened twice.

The first time, we had to restore 4 small databases.
The second time, only one database was affected. Since that database is large (15 000 000 rows), it took time to restore it.

The main web server has been connected to another, but smaller UPS until we receive a new one this week.
