These services won’t all be offline simultaneously, but each will experience a brief (less than 5 minutes) outage while the server hosting it is rebooted to apply operating system patches.
UPDATE
[2008-12-19 00:12:47 | Emrys Ingersoll]
Server maintenance completed successfully for the servers hosting the EECS website, FTP, Jabber and Sympa services.
However, the Sympa web interface was unavailable for about 15 minutes due to a file permissions problem and Jabber was unavailable for about one-and-a-half hours due to an issue with its SSL certificate.
My apologies for the extended outages of Sympa and Jabber. I hope they didn’t cause any inconvenience.
