It helps maintain system responsiveness by avoiding long waits for failures.
In distributed systems, 'failing fast' ensures that resources like threads are not tied up waiting for failed services to respond. This keeps the system responsive. For instance, in a microservices architecture for a travel booking site, 'fail fast' ensures that if the flight booking service is down, users quickly receive an error, rather than waiting indefinitely.
