I'm reliably informed that the powers that be at H.M. Treasury have, for reasons best known to themselves, deemed this very site to be Not Safe For Work. I.e. it would appear that you can't browse to this site from computers on the Treasury's network.
I would imagine the goatse (and perhaps tubgirl) references have something to do with this. Perhaps, though, the scripts on the Linux page were deemed too dangerous for the number monkeys working for Her Maj. to have access to(?). The rumours must be true.
Le'me hear a 'Yay' for censorship!
Update: Turns out my source wasn't as reliable as I had initially hoped. Move along please; nothing to see here.
