Network Outage on 2nd Floor of Soda Hall

by

A network switch on the second floor of Soda had a hardware failure on May 6th between 4:45pm and 5:25pm. The switch serves the instructional lab and instructional servers. We replaced suspect hardware in order to prevent future failures.

A permanent fix will require us to replace the entire hardware chassis and we will announce future network downtime when we are ready to complete the procedure.

Planned network outage, March 25, 7-8am

by

There will be network maintenance at Soda 2nd floor on Tuesday March 25th between 7:00AM and 8:00AM. During this network downtime, both cronus and rhea will be off the network, so departmental NIS and time services will be down. Coeus and Project will be down, so all home directories and project file storage space will be unavailable.

We expect the actual down time to only be several minutes but we are scheduling a larger window for the outage in case we encounter any unexpected problems.

Please make your plans accordingly.
