I am trying to browse the new site and i am trying to buy Outcast, and at every turn the page is being lost, or the site is just very very slow...

I would say the publicity stunt worked too well and GOG are currently being overwhelmed with visitors!

Yeah, that's pretty much what happened. :)

The site seems to be working fine again (at least compared to how it was a few hours ago), so it might be worth another try now.
