I will be upgrading the cloud-vps openstack install on Thursday, beginning around 16:00 UTC. Here's what to expect: - Intermittent Horizon and API downtime (maybe an hour or two total) - Inability to schedule new VMs (also for an hour or two) Toolforge users will be unaffected by this outage. Existing, running services and VMs on cloud-vps should also be unaffected. In case you want to follow along at home, this is tracked as https://phabricator.wikimedia.org/T356287 -Andrew + the WMCS team
