I was recently looking at buying a 3x3x2 from Popbuying and when i go to the Popbuying website, it gives me the whole
"Oops this link appears to be broken." deal and it does the same thing with Google Chrome, Firefox, and IE.

Is Popbuying blocked in Canada or something??

According to DNS, they are hosted by < http://fdcservers.net/ >, who seem to still be up at the moment. I suspect either temporary server trouble, or someone forgot to pay the bill.

the site wont even load for me right now

The site was down for a short time for me as well, but it was a temporary glitch. It's back up now.
