Incident description
During the testing CloudBolt configuration was applied to our configuration management (Puppet) server, which changed configuration on some nodes pointing them to wrong environment (test instead of production). CloudBolt in this configuration, is seen by Puppet as ENC (External Node Classifier). The ENC pushes some configuration to all the servers managed by puppet, and when you use a ENC, you cannot switch the configuration back, and it must be done from CloudBolt. This caused the services to pick the configuration from wrong environment that caused the outage.
Some other production services environment was also pointed to test but there was no loss of service as the configuration for test and production was same.
Incident severity: CRITICAL
Data loss: NO
Cause
Failure to follow the change management process - needs further invetigation.
