Because of the continuing Spectre branch prediction vulnerabilities in modern microprocessors yet another update of the departmental servers coxeter, sphere, and the mail, web, share, and ptr servers will be applied on Wednesday afternoon, May 23, 2018 which will require rebooting (most servers will be unavailable starting at 4:15pm). 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.
Updates at 4:15pm on Wednesday May 23, 2018
