At 11pm on Wednesday evening, we will be taking down our primary mail server, Treehouse, for minor maintenance. We'll be installing software updates and a fibrechannel card, which will permit Treehouse to use our new Xraid for storage. We don't anticipate downtime lasting more than ten minutes, and will post again when the process is complete.

No mail will be lost; sending servers usually retry after several minutes, then again every few hours for 1-3 days before returning mail. Mail that misses delivery during this maintenance window will be delayed, but should arrive shortly afterward.
