There is an upcoming data center outage in the room hosting the CHI@UC resources set for Friday, September 6, 2019 at 4PM CST through Monday, September 9, inclusive. This work requires that the cooling for the data center will be offline during this time while the building management brings another cooling system online, thus CHI@UC will be unavailable for this entire time. We don't currently have an estimate on the exact time CHI@UC will be available again, but we will post an all clear message once we are back online.
