Brief scheduled maintenance Friday, April 3 (completed)

At approximately 11:00 PM Pacific time on Friday, April 3, the “flexo”, “mom” and “elzar” servers will be restarted. As a result, Web site and e-mail service for some customers will be unavailable for approximately five minutes.

No e-mail will be lost, of course; incoming mail will just be slightly delayed.

We apologize for any inconvenience this may cause. This maintenance is necessary to install an updated “kernel” on our servers, as described in an earlier post.

Update: We’re also going to include the “zapp” server in this maintenance to replace a disk in the RAID array.

Update 2: The maintenance was completed with less than five minutes of “downtime”.
