SCHEDULED SHUTDOWN: Please be advised that on Mon, May27th (7am) through May 28th we will shutdown the datacenter to finish the Generator/UPS tie-in work, and also do the spring cooling tower maintenance at the same time. The first day there will be a full power outage to do the final work on the main electrical panel and switch over the chiller and original UPS. The second day we should have the UPS power back, but no compute or cooling until the new UPS is brought online, which will then feed most of the cooling infrastructure
