Following an investigation in to yesterday's performance issues with our UK Cloud, we have discovered a serious issue with memory management which could cause many nodes to crash if left unpatched. Luckily we have a patch in place, however we must issue a reboot of all cloud servers to fully apply the patch. We are therefore marking our UK Cloud 'at risk' while we schedule reboots throughout the next 24 hours.
In the interest of customer satisfaction we will try to schedule reboots at the least busiest time of each cloud server based on its 24 hour bandwidth usage pattern. We appreciate your support and apologise for any inconvenience these reboots may cause.
