#3This strikes me as a huge amount of custom code and technical debt. Every new software dev probably has to learn this.
Why not a sticky master election per user, and have no special data centers?

From what I have read, they only have ~30 employees. They're not exactly onboarding a lot of new people here.

idk, they probably tried to get people on DC's as close to their location as possible. Using your phone number's country code might seem like a good way to do this at first, and they probably didn't give it much more thought before building the whole thing on this idea.

It makes sense: European users are assigned to EU data center, and Chinese to the one closer to them. The "custom code" should not be complicated, just a map of country to DC.
You are suggesting to develop a compicated solution (spend money) when current simple one is working ok without any elections.

#10DC2 is the first connection point of all MTProto clients.
Any DC may refuse a request and force the client to switch DC.
Profile URL doesn't show where messages/chats/channels are stored, as telegram has two dedicated DCs mostly for media. The rest DCs allow media with bandwidth being throttled.
