the Dot Com MU shutdown was an international operation with join-forces used from many different countries.
What makes you think that if "US govt" wants to access/shut down your domain/servers that are Europe-based, they won't ask their French, UK, German, or any other European country allies for help?
Asking an ally for help and simply sending out a "please turn over that data, mr Zuckerberg" is quite a difference. One is top diplomacy, interpol, the whole shebang. The other is something plenty NSA people can do on a whim.
