Topic 1 Question 27
You are running an experiment to see whether your users like a new feature of a web application. Shortly after deploying the feature as a canary release, you receive a spike in the number of 500 errors sent to users, and your monitoring reports show increased latency. You want to quickly minimize the negative impact on users. What should you do first?
Roll back the experimental canary release.
Start monitoring latency, traffic, errors, and saturation.
Record data for the postmortem document of the incident.
Trace the origin of 500 errors and the root cause of increased latency.
