If even Google can go down, nobody is safe.
On Friday May 15th at approximately 6:30 PM one of the circuit boards went out on one of the three hard drives in our mail server. Our technicians worked quickly to repair the problem.
Unfortunately, the screws on the hard drive are a rare Torx type of screw. Our technicians had to track down the proper toolset to remove the hard drive.
Our mail server is running in what is referred to as a RAID5 configuration. What this means is that there are three hard drives in the server that share all of the data on the system as a single drive. We can lose two drives and not lose any data, because that data is shared across the three.
Once the hard drive was repaired the RAID array took about half an hour to rebuild and mail functions were restored around 10 PM. Any e-mail received during this time was eventually delivered over the next couple of hours.
We apologize for the downtime. With the new controller board installed on the hard drive we hope to avoid such situations in the future.
