I've gotten a request to produce a version of EC2 for Poets for people in Europe. Of course I will do it, but it never occurred to me that an AMI that runs in the US won't run in Europe.  

Skimming the docs that are available, it seems this is a security thing. If your servers in the US go down, they won't necessarily take down your servers in Europe? Not sure. 

Anyway, if anyone has any tips on how to create a European fork of a Windows-based AMI, please post a pointer as a comment. Thanks!
