Internet outage at CloudLab Utah on April 16

[Robert Ricci]

Our upstream network provider at Utah is doing a hardware upgrade on
April 16 from 11 PM to 3 AM. During this time, the CloudLab Utah (and
Apt and Emulab) cluster will be cut off from the Internet. Nodes should
not lose connectivity to our control servers or each other, so they
should be in a working state when Internet connectivity is restored.

To add on to this, we expect that the CloudLab portal as a whole will be inaccessible as well.  Please plan ahead to ensure you don't lose important data due to expiring experiments.

Who is he new upstream provider?  I assume this is happening at the downtown location.  Glenn

Glenn:  This is a UETN router that's being upgraded, and it will take the entire Science DMZ offline.  In our case, that means Emulab, POWDER, CloudLab Utah, Apt, as well as the Portal for every cluster.
