Referring to https://www.drupal.org/project/health_check
I am confused as to what 'If Drupal fails to bootstrap' means.
What is term 'bootstrap' referring to? Does it make a database call? From what I have read bootstrap can mean from the Drupal core.
So if the healthcheck module fails is it because it cannot see the database, will the module render a 200 or some other response code?
