Malaysia started mandating ISPs to redirect DNS queries to local servers

With HTTP/3 there isn't much higher level packet analysis to do between anything useful in the headers being encrypted and the session being reused. All you see is there is a 443 UDP session to a Google server and encrypted packets keep getting sent back and forth... which looks exactly like any other HTTP/3 session to a Google server.

I think the weak points are wholly untechnical e.g. Google would often give in to protect the $$$ they make in a region.

Packet size (i forget if http/3 does padding) and packet rates are still available, dns looks a lot different than most http content.

In terms of packet size, DNS (DoH) doesn’t really look any different to an XHR request.

Request maybe, DoH responses are probably way shorter than anything else though.
