Missed security update led to 9 1⁄2 hours public healthcare service outage on Oct 13

By · Published by Everything Blog

In short

The Oct. 13 disruption struck SingHealth, National University Health System, and NHG Health simultaneously, preventing automated bookings, visitor registrations, and medication dispensing. Approximately 4,000 outpatient appointments had to be rescheduled as staff shifted to read-only records and paper-based procedures. Redundant data centres proved ineffective during the crisis because both relied on the identical DNS configuration that failed to receive the required update. In response, Synapxe and the Health Ministry are reviewing contractor agreements and forming an expert panel to reassess technical fail-safes.
