Alert Message: 

This test was successful. The test demonstrates that if the Morningside system is not functional the Syracuse site will automatically start handling email instead. Inbound email was received through the Syracuse site from 10:42 to 10:55, when the Morningside site was put back in service.

-----

On Saturday January 7 between 10:30 a.m. and 1:00 p.m. CUIT will conduct a failover test of the inbound mail system from the Morningside servers to the Syracuse servers and back again. We have verified that the Syracuse servers are fully functional and we have previously tested the failover with non-production systems. No outage is expected. After a successful test we will enable automatic failover to Syracuse in case the Morningside system should ever become unavailable.
