Check whether a URL is censored in a particular country by using proxies located around the world. Input URLs or text into the top box and choose whether you want to request those URLs via your own browser or through one or more proxies. Each URL inputted will be requested through each selected proxy. Additionally each URL will be requested from our own server in the Netherlands so that a comparison can be made. The proxy list is regularly updated by scraping free online proxy lists such as freeproxylists.com and xroxy.com. Clicking the proxy will open a new tab for IP lookup service whatismyipaddress.com showing additional details about the proxy. If you cannot find a useful proxy you can specify your own in the bottom box (in the form IP:port, e.g. 192.168.0.22:80). Although all listed proxies are publicly available on the web they might not all be made accessible intentionally. URL blocking is mostly intentional and web traffic from a proxy to a blocked site may have consequences for the owner of the proxy. Consider the political situation in the country of the proxy you are using w.r.t. the types of URLs you want to request through the proxy. This will be added to Social Informatics Subject Tracer™.
