On Thursday morning, May 7 at 5:00am, ITS staff will be performing network maintenance on a large number of servers in the datacenter. Each system will experience a 15-20 second network outage. We expect there to be zero user-visible impact from this work; however, it is possible that some systems will go offline temporarily. We will make every effort to minimize this disruption; all affected systems will be back online no later than 6am.
