Dear DDM Company Admin, What is this notification about? This notice is to update you on the Microsoft incident which was impacting the DDM Production Market Service. Progress update Microsoft advised CTI that a high volume of requests to their UK South Region caused slowness in their Defender service. They have since scaled up their infrastructure to handle the increased traffic, which appears to have mitigated the impact on the DDM application. What action must I take? Please cascade this information to the DDM users within your organisation. Next update A further update will be issued tomorrow once we have seen a prolonged period of stability on DDM.

Following confirmation from Microsoft yesterday afternoon that they had scaled up their infrastructure to handle the increased traffic, the DDM production service continues to remain stable and BDX upload/processing is working as normal. CTI are waiting on a formal Root Cause Analysis (RCA) from Microsoft to understand why the increased traffic impacted their services. What action must I take?
