(about 21 hours ago)

All of kraken’s nodes based at Guelph (all the nodes named “nar#”) will be decommissioned as if this Friday, April 29. Our apologies for the short notice.

(6 days ago)

Most of the cluster nodes affected by the power outage have been recovered, we are still working on a few remaining.

(6 days ago)

A brief power outage due to an electrical storm has forced goblin, dusky and parts of kraken offline. We are working to restore service now.

(16 days ago)

Emergency cooling maintenance is scheduled for tomorrow (Tuesday April 11) starting around 10am. All nodes in the affected data centre will be shut down (this affects about 25% of kraken nodes: bul1 through bul159). They have been marked offline but any jobs still running at the time of the outage will be lost.

Mar 20 2017, 03:08PM
(about 1 month ago)

The admin node has been recovered and the cluster is operating normally again.
