The departmental servers are working fine after the updates.

The departmental servers coxeter, sphere, and the mail, web, share, ptr, and blog/wiki servers will have software updates applied on Wednesday afternoon, July 30, 2014 which will require rebooting (most servers will be unavailable starting at 3:45pm). Since some updates will be applied while the servers are still up there may be some temporary issues with some software. We hope that any such issues will be minor and by doing most of the upgrading before bringing systems down the shorter downtime will be worth the potential minor problems. Please restart any programs if you observe problems during the upgrades (and please let us know at requests@math.toronto.edu, so we can investigate). We expect the systems to be back up by 4:30pm.

The departmental servers are working fine after the updates, which finished just before 5pm.

After testing we have determined that the update of the mail server will likely take an extra hour due to filesystem maintenance.  Because of this the mail server will be going down at approximately 3:15pm tomorrow (Wednesday, Feb 19).  The other servers will be going down at the usual time (4:15pm) and we expect all servers to be available by 5:00pm if there are no unforeseen problems.

For increased reliability redundant power supplies were added to coxeter and sphere and they were attached to redundant UPSes.
