Site is currently online and fully functional again, after the problems earlier mentioned. I've spoken to the PS3Key team, and to quote them; "We are changing servers and fixing some bugs in the site code."
Rest assured that they are aware of the problems and are working to get it fixed permanently. In the meantime, if you need updates for either Atmel or Silabs versions of PS3Key, and you are for whatever reason unable to login at the PS3Key site, you could do worse that searching here at PSX Scene - or try your friendly neighbourhood Google search engine.
Also, as a side dish - please refrain from moaning about the PS3Key in this thread, there are hundreds of others you can choose from - it's to keep members informed of the status of the PS3Key *SITE* and nothing more.
