Fwd: [Power Outage] SCS Wean Hall machine room - March 8th

[Predrag Punosevac]

Dear Autonians,

This is a gentle reminder that power outage in the Wean Hall machine
room has been scheduled for Wednesday March 8th. I am planning to
gracefully shut down all our servers Tuesday March 7 around 9:00 PM.
Please plan on not being able to use servers for 48h (worse case
scenario).

Best,
Predrag

Hi All,

Thank you to everyone who provided feedback.  The power outage in the 
Wean Hall machine room has been scheduled for Wednesday March 8th.

New equipment is coming in the door this week and there is a pressing 
need to get it into production as quickly as possible.  We can't deploy 
new GPU servers until this work is completed.

We expect all systems/clusters to be back online and functional before 
the end of the day on March 8th... this should be a relatively short 
interruption in service.

Thank you once again for your patience and your feedback.

-Ed
