Hi all,

Apologies for the short notice.  We were told that there will be a roughly 10 to 20 second power outage affecting the Emulab Cluster on Thursday, July 17 at 6 AM MDT.  Emulab experiment nodes (pc3000, d710, d820, d430) will reboot, along with most of the management, control, and experiment network switches at Emulab.  Our core infrastructure is on UPS and should weather the outage, but you may find yourself briefly unable to access the CloudLab portal at that time.

As always, we encourage you to save off important data from your nodes prior to the downtime, in case of any hardware issues following restoration of power.

Best,
 - Aleks

Hi all,

Just a reminder, this power bump is happening TOMORROW, on July 29th at 6 AM MDT.  This is expected to be a 10-20 second outage that will cause Emulab experiment nodes (pc3000, d710, d820, d430) and most Emulab switch infrastructure to reboot.  Our core infrastructure is on UPS and should weather the outage, but you may find yourself briefly unable to access the Emulab portal at that time.  Please make sure you have saved off any important data from your nodes in case of any unexpected issues.

Best,
 - Aleks
