I'm going to upgrade the labs infrastructure from Openstack
Havana to Openstack Icehouse on this Wednesday, November 17th. I'll
be starting work at 9AM my time, which is
<meta http-equiv="content-type" content="text/html;
charset=ISO-8859-1">
15:00 UTC. The whole process should only take a few hours, but it's
hard to predict. I'll be on IRC for the duration of the upgrade.<br>
<br>
This should not produce any service interruptions on labs
instances (or tool labs.) There may be brief interruptions to
network service or DNS, but I don't expect them to be noticeable.
If you DO encounter serious changes in instance behavior, please
look for me on IRC.<br>
<br>
During the upgrade there will be sporadic interruptions in the
OpenStack API as the various components disagree about API
versions. That means that wikitech's lab control interfaces will be
even more unreliable than ever.<br>
<br>
If at any point during the upgrade it looks like instances
suffer extended downtime, I'll halt the upgrade and regroup. Keep
an eye on this list for updates.<br>
