// The code re-tries fetching data if it gets status 429, which is the error that the SJ page has
// It does this together with an exponential back-off delay which is common to use with microservices of this type
// Because of these re-tries and the delay, the overall load of the website and the servers will be lower,
// since it does not need to re-fetch requests that actually succeed. Read more on my twitter if you're interested:
