For the past 8 months we've been working on building a series of probes;

- Android https://play.google.com/store/apps/details?id=uk.org.blocked...

- Python https://github.com/openrightsgroup/OrgProbe

- Raspberry PI images https://github.com/openrightsgroup/lepidopter)

And an open API to power them: https://wiki.openrightsgroup.org/wiki/Censorship_Monitoring_...

This is helping to build a picture of what the UK Governments Internet Blocking/Filtering/Censorship actually looks like.

You can submit URLs to be tested by visiting https://www.Blocked.org.uk by installing the Android app or by tweeting a URL with the hashtag #IsBlocked

Once we receive a URL it is dispatched to all probes over a period of time where it is checked against a know list of blocking methods.

The results are returned back to the API for public evaluation.

For example: https://www.blocked.org.uk/results?url=https%3A%2F%2Fnews.yc...

Please help us build a picture of UK Internet Censorship by adding URLs to be tested, by helping develop new probes (browser extensions, an iPhone client etc etc) or just by spreading the word that https://Blocked.org.uk is available.

Please also see https://www.blocked.org.uk/faq which will explain the level of filtering enabled on some of the probes which will explain why some sites may appear blocked even if you, being on the same ISP, can reach said URL.
