    After down detector went down with the rest of the internet during the Cloudflare outage today I decided to build a robust, independent tool which checks if down detector is down. Enjoy!!

    Yes, it's open source: https://github.com/lissy93/web-check :) Why I'm building this? There are a lot of tools out there for discovering meta and security data relating to a website, IP or server. But currently, there isn't anything that does everything, all in one place and without a paywall/ user sign up. It's still a WIP, and I'm working on a new version, with some more comprehensive checks, so any feedback would be much appreciated :)

    whenever I click through to a site managed through cloudflare I end up seeing a screen asking me to identify myself. This has happened often enough especially with HN articles that I just close some articles outright and read the discussion on HN instead. As an experiment I setup cloudflare for website of mine which gets majority of its traffic from Pakistan (where I am located). This is what I see https://dl.dropbox.com/u/8037186/cloudflare.png It basically shows cloudflare marking 100% of traffic from Pakistan as known threats. I would be interested to find out if its a common problem…
