SciNet/Niagara Downtime Announcement March 25-26 2020

All resources at SciNet will undergo a two-day maintenance shutdown on March 25th and 26th 2020, starting at 7 am EDT on Wednesday March 25th. There will be no access to any of the SciNet systems (Niagara, Mist, HPSS, Teach cluster, or the file systems) during this time.

This shutdown is necessary to finish the expansion of the Niagara cluster and its storage system.

We expect to be able to bring the systems back online the evening of March 26th.
