They are constantly "Temporarily sold out", at least in European regions.

They are available, but only in NY and one more (not sure which). I have confirmed this with their support. I am not sure if they are planning to introduce them in other regions anytime soon. I think NY is pretty much a good global location for America + Europe markets.

Agree that for a western English audience NY is the best location reaching both the US and EU with a ok latency.
