Unfortunately, our DNS servers went down a couple of weeks ago. DNS is how IP addresses get translated to alphanumerical addresses, and there is a thing called "DNS cache". Even when we got the problems fixed, most computers (if not all) that tried to access pinkfloydfan.net when it was down had the non-functioning DNS address cached.
To sum it up, it may take anywhere from 12 hours to several days for the DNS cache to be refreshed, which is why you (and myself!) are now able to access APFFN, but you had trouble doing so for some time before.
I'm really sorry about this and any inconveniences (including any abstinence syndrome symptoms) this may have caused you.
Cheers,
Paulo
