We had an issue this afternoon with one of our data centres that affected a number of servers. The majority of the servers were back up and running quickly, roughly 8 machines booting per 10 seconds, but a number had to go through the check disk process which can take some time.
If a server has not been restarted for more than 150 days then the file system check is forced which in some cases can take quite a while to process.
All servers are now running and normal operation restored. If you are seeing any issue then please open a ticket from your client area.
