The audio file server is still inaccessible. The main server with these domains was out for around 10 hours, due to a network problem at my providers, and a related problem is probably what is still affecting the audio server.
Unfortunately my providers are not responding. Once again their incredibly 24/7 support team decided to go home with my second server still down. They should be back in the office now, but are ignoring my mail and service tickets.
I don't think I can get this set up quickly, but I'm looking into moving the audio files to LibSyn. I am trying to find some technical documents etc. to make sure that they can support what I want, but I will probably move over the weekend (which I'm not happy about as I wanted to get out with the new 100mm F2.8 IS Macro lens!!
Anyway, sorry for the inconvenience. Hopefully I'll be able to get this sorted out once and for all very soon.
