Sometime soon (probably in the next day or two) we will be applying
kernel patches to all VMs and physical hosts in WMCS. This is to address
an urgent security issue[1] , so we'll be skipping the traditional 7-day
warning period -- basically as soon as proper fixes are available we'll
start patching and rebooting.
As usual, we'll do our best to re-balance Toolforge grid nodes, so
impact on Toolforge users should be minimal (worst case you may need to
manually restart interrupted tasks).
For other users: if your VPS project requires special handling or
specific notice about when a particular VM will reboot, please add a
subtask describing your need to
