The Windows Phone web marketplace seems to have gone down a few minutes ago. The issue seems worldwide at the moment, and started around midnight UK time. The issue does not seem to affect the on-device marketplace.
Ironically the problem has occurred soon after Microsoft deactivated the Zune-based access to Marketplace.

Update: Back up now. It seems to have been down for about 2-3 hours, which is of course pretty long.
