The servers hosting the aforementioned services lack redundant connections to the SAN which prevents them from remaining in service during the maintenance. We realize this is an unfortunate limitation and are procuring new hardware which will add the redundancy necessary to handle similar situations more gracefully in the future.
Our apologies for the short-notice and inconvenience.
UPDATE

All of the announced services are back online.
Though the SAN maintenance completed on schedule, there were some technical difficulties on my end which caused services to be unavailable for a bit longer than announced. As a result, the departmental website and FTP server were back online at 6:23 p.m. and the Sympa and Jabber servers at 6:40 p.m.
My apologies for the additional downtime.
