Data Action failing with 502 during BYOC failover in AP-SE-2

Quick question, has anyone seen this weird error? with our custom data action that calls an external CRM API. it works fine 99% of the time but fails hard when we trigger a manual failover on our BYOC trunks in the AP-SE-2 region, returning a 502 Bad Gateway instead of the expected payload. The SIP registration status remains healthy on the secondary carrier, so this seems isolated to the analytics query timing during the switchover.
