Doesn't signal automatically proxy your traffic if it detects that the domain is blocked? I assume signal will just continue to work in Nepal despite their DNS block.
Additionally the comparison of the hand dryers is pretty unfair imo. Those V-shape Dyson dryers are so much better than any others I've tried ever. All the other seem downright anemic (or rather asthmatic in this case) and take much longer than those advertised 20s.
