Symptom

Smoketests failed, and external stakeholders reported errors from NRP services.

Impact

Most NRP services were affected. Requests that depended on calls across multiple internal services frequently failed and returned HTTP 500 Internal Server Error to external consumers.

Root cause

A firewall policy change in the internal infrastructure network blocked internal connectivity from NRP services to the OAuth authorization service.

As a result, internal service-to-service HTTP calls timed out. When request handling required orchestration across more than two services, this propagated as HTTP 500 responses to external parties.

Resolution

The network team at JN Data reverted the firewall policy change, restoring connectivity and normal service behavior.

Actions

JN Data will create a problem management case investigating the following:

• Why the firewall rule change was requested.
• Why the implemented change date did not match the planned change date, which increased time to diagnose and resolve.
