Note on Timeouts, Retries, and Backoff With Jitter via Amazon Web Services, Inc.

When adding jitter to scheduled work, we do not select the jitter on each host randomly. Instead, we use a consistent method that produces the same number every time on the same host. This way, if there is a service being overloaded, or a race condition, it happens the same way in a pattern. We humans are good at identifying patterns, and we’re more likely to determine the root cause. Using a random method ensures that if a resource is being overwhelmed, it only happens - well, at random. This makes troubleshooting much more difficult.
