Issue: Iseult down
Due to an attack of some kind (report to follow after log analysis is complete) the shared hosting server iseult had to be rebooted. Post reboot the machine is now giving a grub error (grub is a boot loader).
We’ve dispatched a Linux engineer to the data centre to fix this issue. ETA is approx 2 hours. So @ approx 19:00 hours we expect the server to be back.
We’ll update this post with more information as we have it.
Update: 18:15
The server is now booting and should return to normal service in the next couple of minutes. The raid array is degraded and is rebuilding, this will affect IO performance for the next hour or so. We’ll dig through the logs tomorrow and see can we find a reason for this issue. It was however (from preliminary examinations) a customer website that was receiving a lot more traffic than normal (typically a wordpress blog without wp-cache installed/enabled) that caused the problem.
