### What Happened

Starting at 13:26 UTC on November 24th Microsoft Azure region eastus experienced a stock out situation, which impacted operations for all tiers of Neo4j Aura in that specific region. Additional capacity was requested straight away, but not until 17:06 UTC on December 10th did enough additional resources become available to resume all normal operations.

How the service was affected

All tiers within the Neo4j Aura Service were impacted when performing the following operations during this incident: Create, Resize (CPU and Storage), Clone, Pause and Resume. If Microsoft Azure resources were unavailable when requesting these types of Neo4j operations, the operation would fail, and the Neo4j instance would become unavailable until Azure was able to provision additional resources.

### What are we doing now

To mitigate the scope of impact of future regional stock out issues, Neo4j is implementing the following measures:

• Closely monitoring resource capacity to improve stockout predictions.
• Regular calls with with our Cloud Service Provider to:

• Learn about where regional resource capacity restrictions are forecast.
• Plan for more resources in restricted regions.

• Investigating other deployment models to allow us to keep Aura running in situations where 3 Availability Zones are not available.
