Good thing that the Telegram client supports proxying traffic over SOCKS5 and MTProto (custom protocol). On the server-side, in the past, they successfully employed domain-fronting and recycling through multiple IPs to bypass the Russian firewall.

The client does its own DNS resolution over HTTPS and so DNS blocks are already ineffective.

It's also capable of masking its proxy traffic as TLS. This works so well you could actually have a web server behind it that would still work through the same port for a regular TLS client.

You can also achieve it with something like sslh and use ssh, https, OpenVPN on the same port. Pretty cool thing. But probably vulnerable to DPI.
