    Confirmed by 2 independent vantage points. Telegram is responding with errors: t.me links. Some requests go through and some do not, which is why it works for some people and not for others. If a message fails to send, try again in a minute; there is no need to reinstall the app.

    The signs were not confirmed. For 15 minutes no second independent vantage point saw the problem, so we are closing this watch. Telegram is working.

    Recovered: t.me links have been responding normally for 5 cycles in a row. The incident lasted 10 min. If it still does not work for you, the cause is no longer Telegram.

19. 2026-08-19 18:17 UTC

    We are seeing signs of trouble: t.me links. So far only one vantage point out of three reports it, so we are not calling it an outage — we are checking. If Telegram does not open for you, wait a few minutes and try again: the state on this page is recalculated every minute.

What it was

We do not name a cause: we have availability measurements, not access to Telegram's infrastructure.
