Overview
- The gob.mx domain experienced a mass outage on August 19, 2026 that returned “500 Internal Server Error” messages and made many government sites unreachable.
- The Agencia de Transformación Digital y Telecomunicaciones (ATDT) posted that a 'corte de conectividad' disabled the domain and announced an estimated 25-minute repair window.
- Affected sites include the Presidency and major ministries such as Health, Finance, Economy, Defense and Environment, which disrupted access to citizen services and transactions.
- A 500 Internal Server Error indicates a server-side failure but does not identify the root cause, and ATDT has not attributed the outage to a cyberattack or released technical details.
- Because gob.mx centralizes federal web hosting, a single connectivity or infrastructure failure can simultaneously halt many services, so investigators will check whether the fault was internal systems, upstream networks or configuration errors.
