web-11 is currently reporting problems and we are rebooting in the hope that this clears the issues.
We expect the server to be restored by 8am
The server was rebooted and came back into service just before 8am.
The cause of the outage appears to have been a locked process causing an intermittent kernel hang. We are investigating the causes of this currently. As part of the reboot (which was being scheduled for a normal maintenance window later this week) a new kernel has been installed which may already include a patch for this issue, and engineers are reviewing the trace logs to ascertain if an additional kernel update will be required
