API - Translator Text: European datacenter

Microsoft Translator is served out of multiple datacenters. These datacenters are located in the United States, east and west coast, in Europe (Dublin, Ireland) and in Asia (Hong Kong). 
Requests to the Microsoft Translator API are handled by the datacenter that is closest to where the request originated. 

Here are two references to Microsoft's Dublin datacenter:

To force the request being handled by the datacenter in Dublin, change the API calls to go to the service endpoint directly, instead of the load balancer:
  •, instead of
  • db4 means Dublin Datacenter #4.
Important information:
  • Customized systems using the Microsoft Translator Hub and collaborative functions (CTF) are not available when calling the Dublin datacenter directly.
  • If you call the Dublin datacenter as described above, the call will be processed exclusively by the Dublin datacenter. If the Dublin datacenter is not available at the time, the call will fail. The call will not be redirected elsewhere. The metadata only, no content, will be transferred to and processed in the United States.
