Data Transfer Inquiry: Loriot LoRaWAN Network Servers

Data Transfer Inquiry: Loriot LoRaWAN Network Servers

Hi.

Could you provide me with more information about the process of transferring data from the middleware endpoint: loriot.middleware.tago.io to the eu4pro.loriot.io network server? 
Considering the fact that there are several Loriot LoRaWAN network servers, how is the data precisely transferred to the correct one, in my case, eu4pro.loriot.io? Does TagoIO send the data to every Loriot LoRaWAN network server, and if this process involves some sort of configuration, is it possible to edit that configuration?

Thanks
