Brief maintenance on calculon server (completed)

The “calculon” Web server will be restarted at 9 PM Pacific time tonight (July 5). This will cause a five-minute interruption of Web and e-mail service for customers on that server.

Other servers will not be affected, and incoming mail will only be delayed, not lost.

We apologize for the problem and for the short notice: the restart is necessary to replace a potentially failing disk in the RAID array.

(This is the second disk on that server that has needed replacing this year. We track these things closely, and we are monitoring it to make sure there isn’t a problem beyond unfortunate coincidence.)
