Probed from a Thai consumer ISP (AIS Fibre): DNS resolves but ICMP and
ports 80/443/8080 are filtered, while app.rid.go.th answers in 0.27 s
over the same connection. Correct the earlier note that assumed the
timeout was a foreign-network block, and stop pointing the dam-feature
follow-up at a host that cannot be reached.
