Does using the .to TLD really imply that the request has to make a hop through Tonga? I'm not a DNS expert, but that doesn't sound right. (I ask as the owner of a .so site...)

I also am not an expert, but Dan J Bernstein (the owner of cr.yp.to) states that his website --- er actually hold on, I think I misremembered the story from his site. Let me paste it here: 2000-11-16: The .to administrators destroy yp.to for reasons that have never been explained. See more here: https://cr.yp.to/serverinfo.html https://cr.yp.to/serverinfo.html

  That's quite an interesting page. They had a recent outage after 3 years > 2017.07.24 roughly 21:50 to 22:10: Unexplained network outage at UIC. > 2020.04.20 roughly noon GMT: Power outage at UIC.

    Hehe, UIC is the bane of cr.yp.to's existence, between network and power instability... Makes you appreciate what the big cloud players abstract away from us!

Short answer, No... Long answer, 'sort of'. DJB uses a custom nameserver for DNS, so only one of the lookups would have to go through Tonga. The web request wouldn't leave the US (assuming that's where you are). It goes sort of like this: 1. You query 'cr.yp.to' which your DNS server will either have cached, or make a recursive query to '.' (root DNS), then to '.to.' The '.to.' server will have nameserver information for 'yp.to.' which gets queried next. 2. The nameserver for 'yp.to' is looked up. In this case, it's `uz5jmyqz3gz2bhnuzg0rr0cml9u8pntyhn2jhtqn04yt3sm5h235c1.yp.to.' 3. The A records for that NS record are '131.193.32.109' and '131.193.32.108', both of which belong to an IPv4 block owned by the University of Illinois at Chicago. 4. Your computer queries the A record(s) for the subdomain, 'cr.yp.to.' from the nameserver for 'yp.to.' which in this case points to the same two IPs as the nameserver. 5. Depending on your OS/Browser, you will make an HTTP or HTTPS connection with that server and begin to download site content. So, no you don't "make a hop" through Tonga, but the '.to.' nameserver will receive a request (if it's not cached by your resolver) to resolve the 'yp.to.' server.
