Due to a cooling plant failure last night around 11pm, the clusters (IITAC, Lonsdale, Parsons) performed an automatic shutdown of all compute services to prevent damage.
All running jobs were lost. The file storage was not affected.
Following maintenance work by the Buildings Office this morning, we have resume service on Lonsdale and Parsons, and are actively monitoring the cooling situation.
Update Wednesday 25-Aug-2010 2pm
IITAC is now available again, as the cooling has stabilised.
