   Confirmed: t.me links does not open in United Kingdom. Elsewhere it works. Why it fails there we do not know. If you are not in those countries, this does not affect you.

    Looks like trouble is starting: t.me links. We are checking. If Telegram does not open for you, wait a few minutes and try again.

What it was

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