Replace geolocation API

[david-mears-2]

We had been missing app_loaded events because the Kamero API deployment had been 'paused'. Other events were still coming through (though they will have been missing their location parameter), which clued me in that something was wrong (it wasn't just that people stopped visiting the site).

ipwhois seems like a more production-apt service, since it comes with a 99.99% uptime SLA. On the free tier we get 1000 requests per day.

Evidence that this code now works: you can see it coming through for localhost on Posthog, with the correct country: https://eu.posthog.com/project/128512/events/019f89b7-b309-7f70-b443-257ef31ab96a/2026-07-22T12%3A05%3A45.386000Z

Added an annotation to the posthog dashboard:

📝 Walkthrough

Walkthrough

The geolocation endpoint now uses ipwho.is, with inline documentation added. The Analytics README description removes the previous provider attribution while retaining the existing coarse-location and Posthog flow.

Poem

A rabbit hops where new URLs gleam,
Ipwho.is joins the data stream.
Old names fade from README lore,
Coarse country clues remain as before.
“Nibble and browse!” says the hare with delight.

app_loaded is emitted independently of the external ipwho.is response; handle
the lookup as best-effort or proxy/cache it server-side, ensuring provider
failures, limits, or outages cannot suppress app_loaded.
