Intermittent 5xx errors on Apps in Europe region

As part of our ongoing efforts to improve system performance and reliability, we recently upgraded the Istio service mesh across our Kubernetes clusters. This upgrade included changes to the default retry behaviour for intra-cluster communication.

Following the upgrade, we identified and resolved sporadic 503 errors by updating retry configurations for affected applications. All systems are now stable, and we continue to monitor performance to ensure reliability.

Thank you for your patience.

The system has been stable after applying the mitigation. The investigation is still in progress to resolve the root cause. We will provide next updates soon.

We have applied a change at the compute layer to mitigate the issue. We will be keeping the system under monitoring and will continue the investigation on root cause.

Customers in Europe region may face intermittent 5xx errors in Apps service. We are currently investigating this issue.
