The stats server is now back up, but I’ve already ordered and am in the process of setting up a new server so will continue with that.
Once that’s set up, it may take some time for the DNS settings to update, but both servers will be active simultaneously.
The new server should mean that we don’t have the same problem again.
UPDATE: Unfortunately, it seems like the graphs wouldn’t transfer across to the new server for some reason, but as it has only been a few days since the last issue which resulted in the loss of graph data, not a lot has been lost this time. On the bright side, the new server should be much better as we’re using much higher quality hardware this time.
