As part of routine security maintenance, we'll be rebooting all VMs and virtualization hosts next Wednesday starting at 14:00 UTC (7AM San Francisco time). Toolforge users should be largely unaffected by this activity. Other projects (including deployment-prep) will experience sporadic downtime, a few minutes for each interruption. The entire process will take several hours.  If you need a to-the-minute advance schedule for any particular reboot, please let me know and I'll put your system at the start. -Andrew + the cloud team
