I
did actually wonder if it had been deliberately blocked the first time

but no, there's no warning pop up box (which we do get if a site has been blocked) - sadly all I get everytime I try is a completely blank (white) page but IE dislays that small satisfied "DONE" down on it's status bar as if to say "I'm doing my bit".
Bintel's online shop
used to work for me here though ..... weird!
I just keep my Bintel browsing to home and trawl through Andrews, AOE, MyAstroShop, etc, etc, here now.
