Europe - Composer - Experiences targeting custom fields are failing

An infrastructure update to the EU environment introduced an incompatibility that prevented Composer from retrieving Custom Fields. The issue was limited to the EU region and did not affect other environments. The update introduced a behavioural change in the network routing layer where a configuration setting that had previously been relied upon was no longer honoured under the new setup. This incompatibility was not detected during pre-production testing, as the test environments did not fully replicate the conditions needed to surface the issue.

The root cause was identified and the configuration gap was addressed promptly. Piano is taking steps to improve parity between pre-production and production environments and to strengthen the validation process ahead of future infrastructure changes to prevent similar issues.
