Web (www) server update at 3:45pm on Wednesday August 30, 2017

An update of the web server, www, will be applied and the server will be rebooted starting at approximately 3:45pm on Wednesday, Aug 30. Some updates will be applied somewhat earlier if it appears that the impact on the system should be minimal, so minor software issues may be noticed. 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 that the web server will be back up by 4:30pm if there are no unforeseen problems.
