An issue during an upgrade to our API caused parts of it to go partially offline. The containers and services on one node of the cluster were not accessible, and caused intermittent issues on some requests to some parts of the API.
The Console and UI were intermittently offline for approximately 3 hours. There was no impact on production site availability.
The issue was limited to one node of the cluster, and that node was disabled to fix the immediate customer-facing issues. The underlying issue was resolved, and the node returned to service.
