Telegram

Telegram is a cloud-based messaging platform founded in 2013 by Russian-Born entrepreneur Pavel Durov and his brother Nikolai, originally in Saint Petersburg and now headquartered nominally in Dubai. It supports channels, groups, and direct messages with optional end-to-end encryption, and has grown to over 900 million monthly active users globally. Its combination of large public broadcast channels, minimal content moderation, and strong resistance to government takedown requests has made it the default platform for wartime information in multiple conflicts.

In the Russia-Ukraine war, Telegram became the primary channel for military bloggers, Ukrainian official communications, and independent war correspondents on both sides. Russia blocked the platform on 1 April 2026, ordering users to the state-controlled alternative Max, in a crackdown ISW assessed as producing harsher backlash than Moscow expected: prominent pro-war bloggers publicly declared the war could continue for 100 years at the current pace. Separately, Russian drone recruiter Alabuga Polytech used Telegram to advertise for an unmanned-systems brigade, targeting video gamers via the platform's reach into young male demographics.

In Iran, Telegram has become central to the internet-censorship story. In May 2026, Iranian official Mohammad Sarafraz disclosed that Chinese Deep Packet Inspection hardware had already arrived in Iran, designed to enable a tiered, switchable censorship architecture that could seal off Telegram and other platforms at will without paralysing commercial traffic. The platform's resilience as a censorship target in both Russia and Iran reflects its architecture: channels are hosted on Telegram's own servers rather than users' devices, making content takedown dependent on Telegram's cooperation, which Durov has historically refused.
