tl;dr: Telegram's t.me domain, used for user/channel links, has been placed on "serverHold" status by the registry, effectively suspending it from DNS resolution. WHOIS records show the domain — registered via GoDaddy with Domains By Proxy privacy protection — carries multiple prohibitions on deletion, transfer, and updates, suggesting a registry-level enforcement action rather than a registrar issue. The domain itself remains registered through 2035.
