Server updates at 4:00pm on Thursday April 23, 2015

The departmental servers coxeter, sphere, and the web, share, ptr, and blog/wiki servers will have software updates applied on Thursday afternoon, Apr 23, 2015 starting at 4:00pm 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 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 5:00pm.
