A stored result of a computation, served instead of recalculating it. It can exist at multiple levels simultaneously: in the browser, at the CDN provider, on the server, in the application, and in the database.
Why it matters
Cache determines the speed of a service, but when changes are made, it can become the source of 'I fixed it, but nothing changed.'
What's missing without it
Without awareness of how many layers exist, diagnosis ends with 'but it’s already gone from the database' — while the page still shows the old content.
When it is used
Whenever a change is made that isn’t visible on the page, and when cleaning up after a breach.
How we use it
When cleaning up after an incident, every layer must be cleared. Even one missed layer can cause deleted content to continue displaying.
