I noticed the forum was down on Friday, and assumed it was Pluggy and Supersparky doing the Linux update, so ignored it.

I noticed the router was still up, and the router could still talk to the server, so thought this was the most likely scinario.

I checked again today and it was still down, so checked router again, all ok.  Check SFTP - Could access fine.........HTTP still down.

Decided to reboot server remotely, and the forum has popped up.

Sorry for the down time guys - I truly thought the server was being maintained!
