Please be advised that on Monday May 27th through Tuesday May 28th, the SciNet datacentre will undergo a two-day maintenance shutdown, starting at 7 am EDT on Monday May 27th. There will be no access to any of the SciNet systems (Niagara, P7, P8, BGQ, SGC, HPSS, Teach cluster, or the file systems) during this time.
This is necessary to finish the installation of an emergency power generator, to perform the annual cooling tower maintenance, and to enhance login security.
We expect to be able to bring the systems back online the evening of May 28th. Due to the enhanced login security, the ssh applications of users will need to update their known host list. More detailed information on this procedure will be sent shortly before the systems are back online.
