UZ Brussels Resumes Normal Operations After Network Outage

UZ Brussels has restored its normal operations following a major network outage that disrupted hospital services on Tuesday, forcing the temporary suspension of scheduled operations and the diversion of ambulances to other hospitals.

The technical failure began at around 11:00 a.m. on Tuesday and affected the hospital’s IT infrastructure and telephone systems, leaving it temporarily unreachable by phone.

As a result, outpatient appointments were suspended, the emergency department was closed, and only urgent medical interventions continued. Ambulances were redirected to other emergency departments.

The hospital confirmed on Wednesday at 11:00 a.m. that normal services had resumed. Its partner hospitals are also gradually restoring their systems, including AZ Monica in Antwerp, Heilig Hart Hospital in Lier and Sint-Andries Hospital in Tielt.

UZ Brussels spokesperson Karolien De Prez confirmed that the incident was not caused by a cyberattack and that no data breach had been detected.

The hospital has not yet disclosed the exact cause of the outage, saying its complex IT infrastructure and interconnected security systems make it difficult to provide further details at this stage.

Despite the disruption, the hospital stressed that patient safety was guaranteed throughout the incident and said it would continue monitoring the situation closely.
