Users across Russia and globally reported significant Telegram outages on July 21, 2025, with failures in messaging, media downloads, and server connections. Major cities like Moscow and St. Petersburg were heavily affected, with some users noting mobile data worked while Wi-Fi failed.

Independent monitors like Downdetector tracked the disruptions amid speculation about causes. Technical issues, state-imposed restrictions, or infrastructure testing by Russian authorities (including potential links to new national messenger “Max”) are considered possible factors. Regional blocks in Dagestan and Chechnya since March add context.
