Points and comments are a snapshot, not live.

Telegram routes users to data centers based on phone number country code, not location.

The article's body was unavailable due to a 403 error. The title and comments suggest it analyzes Telegram's data center assignment logic, mapping phone number country codes to specific data centers (DCs) such as DC1-5, with DC2 as the initial connection point.

What commenters are saying

Commenters are divided. Some view the routing as a simple, working solution despite custom infrastructure. Others suspect intelligence alignment, noting DC distribution mirrors Five Eyes jurisdictions. Several cite investigations into Telegram's ties to Russian security services, undermining trust. Critics question Telegram's security claims, noting most chats lack end-to-end encryption unlike Signal.
