Next Wednesday 2019-10-16 at 09:00 UTC we will be doing another maintenance
operation on some of our cloudvirts servers (the hypervisor servers) that
involves rebooting both the physical servers and the virtual machines running on
The reasons is that we ned to update the running linux kernel version they have.
In this window we will reboot 4 hypervisors:
The procedure will be to reboot a server, wait for it to come back online (could
take up to 5 minutes) and wait for all the VMs to come back online. Then move to
the next server.
Toolforge users may see their tools and webservices briefly disrupted due to
several components of the Toolforge infrastructure being rebooted in this operation.
Remainder, this is happening today in about 10 minutes!
