[Labs-l] Labs Openstack upgrade on Wednesday, 15:00 UTC (finished)

[Andrew Bogott]

This upgrade is now done.  There was no instance interruption; the 
OpenStack API was broken for a while earlier in the day but should be 
working fine now.  You will most likely need to log out of wikitech and 
back in to refresh your OpenStack token before acting on any labs hosts.

Please let me know if you encounter any unexpected changes.
