Overview
- Mass General Brigham experienced a systemwide network outage Thursday, October 8, 2026 that pushed hospitals, clinics and care teams off computers and onto paper forms and established downtime procedures.
- An MGB incident command team was activated to coordinate recovery and restoration of services while staff used alternative ways to communicate and document care.
- MGB said patient care continued during the disruption although some elective outpatient procedures were affected as teams worked to bring systems back online.
- Officials said the outage is not believed to be a cyberattack and that staff will update electronic medical records once systems are restored, creating a temporary documentation backlog.
- Watch for updates from MGB on full system recovery and the findings of internal IT reviews that will explain the outage cause and any longer-term operational impacts.
