AWS Cluster DNS Changes Degraded Performance
Resolved MajorIncident Report
Summary AI Generated
MongoDB AWS clusters experienced degraded DNS changes that prevented cluster topology modifications from completing successfully or caused significant delays. The issue was traced to corrupted metadata that disrupted DNS operations and downstream cluster updates. The problem was resolved after 7 hours by patching the faulty metadata, restoring normal DNS functionality and cluster update processes.
DNS changes for AWS clusters are currently degraded. We've identified the issue and are pushing out a patch.
