DNS Belgium incident

The .vlaanderen and .brussels services are experiencing issues.

Resolved after 1 hour 2 minutes, affecting Registration system and Registration system, on March 25, 2026.

postmortem Apr 03, 2026, 05:34 AM UTC

On 25 March between 12:45 p.m. and 14:15 p.m the RDAP and EPP services of .vlaanderen and .brussels were unavailable. This was caused by expired internal certificates. Our monitoring systems detected and alerted the problem, and we took immediate action to identify and resolve the problem. Analysis revealed an incomplete certificate rotation. It was therefore important to rectify this during the incident, which resolved the issues and allowed the services to restart without any problems. To prevent this from happening again, we will further refine our manual procedure and describe the necessary checks more clearly. It is also possible to set up automatic detection for this to guarantee the validity of all certificates.
