Yesterday, one of UVM's primary service load balancers failed. Even though the secondary load balancer restored service, certain parts of the campus network had disrupted connectivity to some services such as the UVM web servers and SMTP. This was related to a complex layer-2 switching problem that is still being investigated.
In the meantime, a replacement load balancer has been provisioned as a primary, and SAA plans to commission this hardware immediately to mitigate our non-redundant configuration.
At 4pm or shortly after, we plan to bring up this new hardware. We don't expect further disruption, however there is a very small chance that some communication problems may result.
