Our systemadministration informed us that we need to powercycle each server to finish updating/patching for a serious operating system bug.
Due to the impact of not rebooting, we are planning to do this this Friday evening, starting a 21:00 Amsterdam time. During the reboot, content that is present in the varnish Caches will continue to show, but dynamic calls such as shopping carts or wp-admin content editing will not function.
Reboot estimations: 2 - 6 minutes.
