Cheburcheck

Checks whether a domain or IP is blocked by Russian internet censorship

Webfreeregional

Cheburcheck is a free, open-source web service that checks whether a domain or IP address appears in Russian internet blocklists, including Roskomnadzor's registry and blocks on popular CDN providers. It's built for people in Russia and researchers who want a quick way to confirm whether a site is censored rather than just down. No signup is required to use it.
