This isn't how technology works. I feel weird saying something so obvious to me but- Servers/databases have IP addresses that can be blocked just as easy to st

  Well, in the case of Telegram they've already tried pretty hard with the servers and databases route (hasn't worked).

    And most servers nowadays are behind CDNs, so blocking an IP might block more than you actually wanted. And with eSNI being pushed, that might become even more difficult to effectively filter a specific service.

  Telegram uses advanced techniques to avoid blocking. You can't just block few IP addresses and call it a day. AFAIK Telegram servers deliver IP addresses of proxy servers via silent Apple Push Notification. Censors have no way of blocking or intercepting those messages. They can only block Apple servers thus disrupting the entire Apple ecosystem from work.

    That really isn't an advanced technique, that's just hiding behind Apple's skirts. The govt is no doubt quite willing to block Apple notifications, and Apple is obviously willing and able to kick apps from its notifications platform. Russia for example is blocking all ESNI traffic... You either downgrade or get blocked. Which makes the big services shutdown of domain fronting so inexcusable, just kowtowing to China and every other regime.
