What changed

3 things changed on telegram.org in the last 30 days.

Certificates expire, DNS gets edited, a header goes missing in a deploy. Prove the domain is yours and we watch it on a schedule — free — and email you the moment something moves, so you hear it from us instead of from a customer.

Signature-based identification from the public homepage. Pattern set is fixed; nothing is sent to third parties.

Server

  • Header value nginx/1.30.1

A certificate that expires on Tuesday should not wait until Friday. Prove a domain is yours and we check it free, once a week, emailing you anything that changed. Pro checks it once a day, looks at every host on the domain, and keeps 365 days of history — so you hear about a problem in hours rather than days.
