## What it is
Falling Sky is the source code for the test-ipv6.com website, a browser-based IPv6 connectivity testing service built mostly with HTML and JavaScript plus a Go-based build tool. It supports multilingual translations via Crowdin and automated mirror deployment.

## Use cases
- check if my isp supports ipv6
- test ipv6 connectivity from a browser
- self-host an ipv6 readiness test site
- diagnose why ipv6 sites load slowly
- run an ipv6 test in multiple languages

## When to choose
- you need a proven, widely used IPv6 test page for users or an ISP
- you want a self-hosted, multilingual IPv6 connectivity checker

## When to avoid
- you need programmatic IPv6 testing from scripts or CI rather than a browser page
- you want a modern frontend stack - this is legacy HTML/JavaScript with an aging Go build dependency

## Facets
- artifact type: application
- maturity: maintenance
- function: http-server, web-scraping, networking, developer-tools, internationalization
- domain: networking, web-development, self-hosted
- platform: go
- tags: ipv6, connectivity-test, browser-based-testing, translations, crowdin, web-server, javascript, linux
