After you click the "Test Account" button, does it return with a green message box that says it took your request and to check back in 10 minutes? Try a different browser. There are some cases where users of IE click on an action and it doesn't really happen.
I just tried and it actually started testing the moment I clicked the button and immediately returned some test results.
Correction Those test results are timestamped from last night. Strange, because I didn't request testing last night. Maybe that was executed during the move last night.
Second Edit A few hours, my test results from earlier actually showed up. Just like the OP's.
