Post-Mortem: Status Page Display Incident
Date: 12/12/25
Duration: 8 Hours
Severity: Low (Display / Monitoring only)
Affected Component: Public Status Page
Summary
An issue was identified where the public status page incorrectly displayed the application as offline. This was caused by a firewall configuration blocking outbound server status checks. The incident did not impact the availability or functionality of the application itself—only the accuracy of the status page.
All core systems remained fully operational throughout the incident.
Impact
- The public status page showed degraded or offline status.
- No customer-facing services, APIs, or internal systems were affected.
- No data loss or service interruption occurred.
Root Cause
A firewall rule was incorrectly configured, resulting in server status and health-check requests being blocked. This prevented the status monitoring service from receiving valid responses, causing a false offline indication.
Detection
The issue was detected via internal review after discrepancies were noticed between operational metrics and the public status page display.
Resolution
- Firewall rules were updated to allow required server status and health-check requests.
- Monitoring was revalidated to ensure correct connectivity.
- The system is currently being observed to confirm consistent and accurate reporting.
Preventative Measures
To prevent similar issues in the future, we are implementing the following actions:
- Review and document firewall rules related to monitoring and observability.
- Introduce automated alerts for failed health-check responses that do not correlate with internal uptime metrics.
- Add a secondary validation check for status page reporting.
Lessons Learned
- Monitoring and observability components should be treated as critical infrastructure.
- Changes to security controls (such as firewall rules) must include validation against monitoring dependencies.
- Clear separation between service availability and status reporting helps reduce confusion during incidents.
Current Status
All systems are operational.
The firewall update has been applied, and we are monitoring results to ensure continued stability and accuracy.
