Hi everyone, The network switch stack used by the oVirt PHX datacenter needs a reboot which is scheduled for tomorrow. It is expected to be a fast task yet it may cut all networking including shared storage access for all of our hypervisors for a couple of minutes. For this reason I'll shut down non-critical services beforehand and pause CI to minimize I/O activity and protect against potential VM disk corruption. Maintenance window: 21.12.2018 20:30 UTC - 21:30 UTC Services that may be unreachable for short periods of time during this outage are: * Package repositories * Glance image repository * Jenkins CI Other services such as the website, gerrit and mailing lists are not affected and will be operating as usual. -- Regards, Evgheni Dereveanchin
