CoursePlus Outage on May 1, 2017
CoursePlus went offline unexpectedly at approximately 1:17am today, May 1, 2017, and was offline until approximately 7:05am. According to the research that CTL and JHSPH IT have done thus far, connections to the database cluster got backed up and caused a cascading failure across the CoursePlus cluster. It is not clear at this time why the connections got backed up or why connections did not fail over to another server in the CoursePlus database cluster, but we are investigating.
We apologize for the inconvenience that this no doubt caused some students, TAs, and faculty. We know that any downtime in CoursePlus is very frustrating to all of you, and we work hard to eliminate unexpected downtime.
