IMSS digital platform outage disrupts employer services in Mexico

On Saturday 20 June 2026, Mexico’s Instituto Mexicano del Seguro Social (IMSS) experienced intermittent failures of its digital services, most notably the IDSE (IMSS Desde Su Empresa) portal used by private‑sector employers to file payroll and worker affiliation records. Users repeatedly encountered an error message reading “Ha ocurrido un mensaje con código #000001: DATOS NULLOS,” preventing the completion of routine administrative transactions. The issue was reported across the capital, the Bajío region, and northern states, prompting complaints on social media and calls for documentation of the outage to justify potential delays in legal filing deadlines. IMSS had not issued an official statement confirming a nationwide outage, although similar technical interruptions were recorded earlier in the year, including an emergency maintenance episode in February 2026. The institute’s technical team continued working to restore stable access to the affected platforms.
