#reachability — Public Fediverse posts

Just added Web Reachability API (at least that’s what I’m calling it) support to https://ip.small-web.org.

It’s for testing the reachability of your Small Web servers (using a domain or, more importantly, an IPv4/IPv6 address). I’m using it to implement Web Numbers¹ support in Auto Encrypt² and Kitten³.

Protocol:

• At http://<endpoint> return an empty HTTP 200 response that includes the following custom header: 'web-reachability-id': ‘<uuid>'
• Hit: https://ip.small-web.org/reach/<endpoint>/<uuid>/
• If you get a 200 response back, your endpoint is reachable. Anything else signals an error.

Enjoy! 💕

So öffnest Du das Kontrollzentrum auf Deinem iPhone ohne vom oberen Bildschirmrand zu wischen
iPhone-Nutzer:innen kennen das Problem: Mit nur einer Hand das Kontrollzentrum zu öffnen, kann knifflig werden. Apple versteck

Reachability Analysis (RA) is a stellar toolbox for safety analysis and safety verification in various contexts, but to name one is autonomous driving and navigation.

@gicycle I'd suggest a critical discussion of #walkability/#cycleability measures and #reachability analyses. Topics like sidewalk width in maps/plans vs real-life usable width might also be eye opening
