Most of the upgrade is complete; however the upgrade has caused an unexpected partial network interruption.  Work on this issue is ongoing, I'll send another email when the issue is resolved. -Andrew We'll be upgrading the cloud services OpenStack install on Monday, beginning at 06:00 UTC The entire upgrade process may take an hour or two.  Early on in the process, Horizon (and associated OpenStack APIs) will be disabled (probably for 20 to 30 minutes.)  There may also be brief network interruptions during the upgrade. Toolforge and existing VMs should be largely unaffected apart from possible network hiccups. This is the second upgrade since October; we are trying to speed up our upgrade schedule in order to catch up with the upstream releases.  With luck there will be further such upgrades in the coming months. - Andrew + the WMCS team
