The departmental servers coxeter, sphere, and the mail, web, and blog/wiki servers will have some software updates applied tomorrow (Wednesday afternoon, May 4, 2011) which will require rebooting. 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 without 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 to be back up by 5:00pm.
Note: We will be doing some blog server application updates starting at 3:30pm so access to the blog servers will be interrupted between 3:30pm and 4:15pm as well as the usual interruption between 4:15pm and 5pm. It is recommended people refrain from editing pages on the blog servers during these updates to avoid losing work.
