Implying overseas servers are already up and running while they just have been announced. We're not even sure yet if Alpha/Beta will takes place on datacenter located outside Japan, so asking for this really?

You'll get the IP the day you'll be able to access the server, there is absoletely no reason for SE to give us anything now. (I don't see the point either).

I want to measure latency with a loaded server. *Remembers EU Battle.net having constant 350ms latency at D3 release because of the server load while the server was physically located near me*
