SQL Server Always On – Intermittent Cluster Failures in Test Setup

I am reaching out to receive support for SQL Server Always On configurations, specifically involving multi-node clusters with geographically distributed replicas in a test environment.

I am currently evaluating the integration of an asynchronous replica into an existing cluster setup for testing. While the primary environment is operating stably, I've observed cluster instability after introducing the new replica node - particularly issues around connectivity, cluster service availability and DNS behavior.

At this stage I am seeking a full solution.

Please reach out the me about the matter and contact me if further information is needed?

Thank you,

Matt
