An update has been applied to Stax's Events service to resolve a bug where AWS-generated events were not delivered as expected.

The Events documentation indicates that AWS-generated events raised in Stax-managed AWS accounts are centralized into the default AWS EventBridge Event Bus in your security account. The actual behaviour exhibited was that events were only emitted to the EventBridge Event Bus for events in the security and logging accounts.

The fix for this bug may result in a material increase to the volume of events received. If you have a downstream system (such as a SIEM) configured, you should consider any volume constraints that may be encountered by this increase in volume.

This fix is being rolled out to affected Stax tenancies over the coming days.

If you have any questions about this change, please contact your Customer Success Manager or raise a support case.
