Downloaded PTR client, but no realms?

I recently downloaded the WoW PTR client and even copied two of my toons. After what seemed like an eternity of updates I logged in, like I usually do for the regular WoW account, but after clicking on "suggest realm" I don't see any realms. It doesn't even say they are down or anything. I selected all the available options but that didn't really make a difference either. Any suggestions as to what I should do to fix this or does this mean I just don't have access to those realms? Did I download the PTR client for nothing?
