My www.direct-links.org domain likes to work sometimes but sometimes it does not. It says the server cannot be found.
Any ideas why?

It hasn't given me that once.
It could just be the quality of the host. Or your location in comparison with the server.
There's a list of possibilities. Best solution would be to get a temporary new host and see if you get the same problems. If not then it's the host, who you would then contact about the problem. If the same problem does occur then it might be something with your internet provider. Find the IP of the server and then I have a file called Ping Plotter which will show your connection to that server from your computer. If there is one fault it will tell you exactly where/which state. All you need to do after that is let your internet provider know and they have to fix the situation. If not just threaten of cancel their services and they normally fix it fast.

*Chris B. thinks it is a namespace issue.

eplxin namespace please. nameservers?

Nameservers, my bad. Check the settings, etc. Sounds like they aren't always resolving.

I'll completly reset the account when I have the time Ian. So get everything backed up.

Back everything up?! :P
That'll take me a day. Email me on confirmation before you do.
