Telegram Unlock Check

Frontend multi-endpoint probes + backend 5-DC TCP handshake verify Telegram reachability. Telegram is a ~1B MAU IM + Channels broadcast + Bot platform + file cloud hybrid, founded by Pavel Durov on Aug 14, 2013, HQ Dubai since 2017. Unique architecture: **MTProto 2.0 self-built protocol** (not Signal) + 5 DCs (DC1/3 Miami, DC2/4 Amsterdam, DC5 Singapore) direct-connected, **no commercial CDN**. **VPN strictness ★★★★☆ (4-star)** — key: Telegram **itself doesn\'t block VPN at all**, the 4-star comes from breadth of national bans (9 countries hard-block + Russia DPI throttle since Feb 2026). ⚠️ **IMPORTANT: Telegram default chats are NOT E2EE**, only Secret Chat is truly E2EE; calls are E2EE by default. Aug 24, 2024 CEO Pavel Durov arrested in Paris, 12 charges, still on trial Apr 2026; Telegram offers official MTProto proxy as anti-block solution (in-app, no VPN needed). IP type barely affects scoring (residential/VPN/datacenter all 30/28/28/28, Telegram doesn\'t discriminate).
