I also noticed that it was down yesterday when I was trying to get an affiliate link from them. Tried to get to the page for some two hours or so before I gave up.

Although.. It seems to be working today.

What maked me a little bit confused is that Paydotcom doesn't seem to have an alternative server to use if one goes down?! I mean.. It's a pretty big actor on the market so even they must loose a lot of money and a lot of trust.
