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.
