The server had been misbehaving again, although it didn't affect this website at all. I had both raid arrays drop a drive and refuse to re-sync. I don't understand why but I think the controllers in the external drives I was using for my back raid arrays were causing issues. Luckily the external drives are just internal drives with a sata controller attached and sealed in a plastic box. I removed the drives and have fitted them in pairs in to 2 drive docking stations. Thankfully they now resync and work as they should, at least for now.
I also had an issue with the second ethernet controller. It refused to work so I replaced it. The replacement refused to work so I put the original one back in and it works great!?! I don't understand why but I don't have much time so I'm happy with it! XD
And now I can get back to trying to move house... ...the long wait continues :/
