Hi HN,I have recently built a small Chrome extension, showing availability of the currently open site. Like you can't open something and want to quickly check, if it is down at all.It checks HTTP responses, DNS resolution and TLS certificate from the cloud environment.For a set of well-known sites it also provides information from official status (e.g. Cloudflare, Airbnb etc.), showing short info about latest incidents, if any.I'm interested in a few things:

  1. In which scenarios would you use it? Own sites, general surfing, quick link to official reports?
  2. Is it worth to extend this official status part, covering more sites? Which services would you want covered? Comments URL: https://news.ycombinator.com/item?id=50325712 Points: 1
