[Kelvin-users] [Lonsdale-users] Service announcement: cluster downtime Friday 21st Nov to Friday 5th Dec

[Sean McGrath]

Dear all,

The Kelvin and Lonsdale clusters are now available for login and access 
to your files. The queue's are still down and will be enabled tomorrow 
morning so jobs will not start being run until then.

Many thanks for your patience during this downtime.
