Slush, is mining on the pool working as there has been no block in over 4 hours, so its either a git block, or something amisss
Sounds like you may still be mining for the old server. Blocks are being found regularly for me here, and the slowdown you're seeing will be because most have switched over the the new.
Check that stratum.bitcoin.cz resolves to 54.214.x.x for you, and then restart your mining processes and you should be up and running on the new
