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.
