Scheduled
Our infrastructure provider has been notified of a potential vulnerability affecting our Virtual Servers. The remediation will require maintenance to the hypervisor nodes and a reboot of all the virtual server instances on those nodes.
Given our redundancy, historically these reboots have just caused a few minutes of downtime while the rebooted nodes recover. We're scheduling a wider maintenance window to account for all the reboots across the entire fleet, however we don't expect more than a few minutes during this time window.
