One of the things on my todo list is to spend some solid time thinking about load-shedding, and in particular tools and methods for small or hobbyist projects to practice it. Like what do you turn off on the site when it's the 15th of the month and you're already at 80% of your SaaS budget?

Like maybe if a request for an image doesn't result in a 304, instead of sending a 200 response you redirect to lower res versions, or just 429 out. How much throttling do you do? And do you let bots still run full speed for SEO reasons or do you do something else there?
