Platform(s) Affected:

Zinfandel

User Impact:

Device disconnections and CSM instability

Underlying Cause:

A slow down in our data structure server caused large increases in response times to requests. This resulted in some requests to time out, and devices to disconnect.

Steps Taken:

The service recovered automatically. As a long term mitigation step, migrations to a data structure with improved failover is expected in 2019.
