Thanks for the well wishes.
Incident Management is where something happens, usually an engineer makes a change that breaks something, and it degrades the performance of the product. Be it a website, news feed, etc. Incident Management is contacted, and we work with other engineers who can fix the issue, or work with the original engineers to revert the change they made to the last known working instance. We then schedule post-mortems for higher-priority incidents to discuss what went wrong and what steps can be taken to prevent the mishap from happening again.
