'Server IP address change' emails
Just a thought for future, I'm not sure if it's possible but could you please state the server name that is affected by the IP change. Whilst no server names are fine for those with just one website hosting hosted (or just using one server) due to hosting a few website hostings I currently have 4 emails in my inbox, two stating the changes are done and 2 for tomorrow. Thus I haven't really a clue, though thankfully I use the nameservers for the domains rather than IPs.
To err is human, but to really screw up you need a computer.
