Currently I'm working on whatports.work in between my studies, basically its an outgoing port tester so that users can test their network's firewall rules. It's similar to portquiz.net, except it has a JS port check, UDP and IPv6 support, and hopefully HTTPS soon.
I've also thought about getting an ASN and doing some anycast stuff. Especially since it's hosted in Sydney currently, which adds a bunch of latency for anyone not in Australia. Also there's a lot of port scan bots, and the server is doing its best to respond to all of them, with some rate limiting of course, but it'll be good to distribute the load anyway.
I can actually see this being useful to me, when I'm setting up a new environment and need to make sure everything available from the wider web. thanks
