Unbelievable, they are still ironing!! Now i'm not an expert on websites (intermetate level asp.net), however I do think that heavy traffic to a site can not cause these issues alone (as said in the media)... it is obviously a website that was not made properly and not tested... at all. Why do companies like this need to lie to the public. Face up to your mistakes and be honest. (this site seems to have full details, however the general media don't seem to). Either way the website should be able to cope with a large volume of traffic.
Another thing is people keep getting told it will be back up by ??/??/?? ??:??... this date and time comes and then goes and still no online shop... if you don't know, then say that!! DON'T JUST MAKE CRAP UP!!
I was seriously looking at changing to 2Deg but the why this issue has been handled is worse that the issue itself.
On a side note... Please continue to boycott Cadbury, there aussie make chocolate is NOT the same as NZ made - ie: Crunchie Choc Slabs, Roses Pepermint just to name a couple of the worst.
