The issue has been identified and we are working with Gothia on a solution. We are working with affected merchants individually hence we are closing this incident.

**Impact:** High - 4 One of 4 nodes partially dropped 3DSecure requests ‌ **Description & Scope of incident:** A change put in place to correct a DNS routing issue affected the connectivity between 1 of the 4 nodes and the connector service related to 3DSecure validation was returning HTTP 403 error. ‌ **Analysis of Incident:** The change put in place to correct the DNS routing issue was silently failing when the required ip configuration of apache2 was blocking it from the new source. In the morning the monitoring showed a high number of declined transactions around 3DSecure for multiple merchants. This was confirmed by Support and Merchants calling in. The changes implemented 27-05-2022 was reverted as part of the rollback procedure and the affected services were restarted.

After extended monitoring we have registered no further issues with increased 3DS declines since the fix was implemented this morning.
