Block Checker

Live

Find out in seconds whether a site is blocked in Russia — or blocks users from Russia.

Block Checker is a pocket directory of blocked resources. Type a domain and see the answer instantly. The app keeps two directories: domains blocked by Roskomnadzor, and websites that themselves block visitors with Russian IP addresses. The database is synchronized regularly with trusted sources, search works by partial name, and a DNS check shows how a domain actually resolves. No registration, nothing to set up — useful for web developers, system administrators and site owners.
