PTR 3.1 Character copy is available on US Realms with a queue downed to 4 days. Seems to be available randomly depending on how many people are copying their characters at certain intervals.  I have been checking every few minutes, reloading the page.

I was able to copy two characters on to Broxigar PvE server. The PvP server is named Anasterian. I will report an update once the installer is available. It is not at the moment. Keep trying to copy your character every now and then. Knowing how many people wishes to join, queues will be full often.
