Alas, we have yet another change forced on us without much notice.
In this case it's a change of IP addresses which seems to have thrown out my Apache build - and possibly uncovered some software incompatibilities. I'm think I'm going to have to build the service from scratch to get it back working, and I might take the opportunity to updaste the hardware as well. This is going to take a bit of time, since I have a lot of other work to do, so I'm putting up this temporary page which should let you get at the data while I build the new site.
Look on this page as a set of temporary traffic lights next to some road works...:(
