If you have experienced problems getting to this site,
were connected but then the server appears to have just died,
only to come back again 15 minutes later,...

Well that's actually a special security feature you're seeing in action.

When any IP address is noted as doing any three "bad things" during a 15 minute window, it's blocked out - the server then appears dead to that IP only. 

This will happen where there have been three attempts to load non-existent web items, missing graphics or pages etc.  That's not only for deliberate hacking in attempts, but also when we've messed up with a reference in the otherwise working code to something that isn't there. 

Therein is a problem which is being worked on now, where this marvelously complex forum template and redirections to the old site have got file locations crossed a bit.  Rest assured it will be fixed soon.  Michael may even have done it by the time I've finished posting this. 

Please do tell us if you experience any further problems (when you can, after any 15 minute block clears, or from another IP  )

In case you're wondering, yes all this is really necessary, the server is constantly being attacked by every means it seems.  The security measure protects all types of access to the server, including anything with a login, and for some types of offence the blocking is indefinite once triggered.  So don't try these servers for any general DNS resolving or mail relaying.  we're having no DNS cache poisoning or spam mail here thank-you very much.

The feature is called "blockip" and it's a program of mine that you can buy and thereby help support the working of this site if you like.  Send me a PM if you're interested.
