I’m planning to reboot OSGeo3 some time in early morning Saturday so hopefully few if any will be impacted.
Details here - #3225 (osgeo3 reboot required for updates etc) – OSGeo
I expect downtime to be around 15 minutes and less than an hour.
I’ll update this note when I am about to do the reboot and after it is back up.
Impacted services are listed here - SAC Service Status - OSGeo
