Forgive me if this is poorly phrased, I’m very much a noob, but if they wanted to block XMPP, is it possible to identify all traffic to any XMPP server/from any XMPP client?
Yes, with deep packet inspection they can identify when a certain protocol is used and then block that traffic. Works the same way as blocking torrents.
Edit: That is harder though than just blocking a couple of IPs that signal uses.
True, but you can also try set up an xmpp server inside the country and sort of fly under the radar as country internal communication is usually less restricted. Of course hosting inside the country also puts the server in reach of the authorities, so better be careful not to collect any data they could get their hands on that way.

thanks!

Is there a way to circumvent such a block?
Tor or I2P would be my guess
Edit: for Tor you will need to use meek-azure because it’s also blocked. idk about I2P, probably also blocked
