Network Timeouts Do Not Imply Server Failure: Effective Retry, Backoff, and Idempotency Strategies

Network timeouts do not necessarily indicate server‑side failure; handling them with appropriate retry strategies, exponential backoff, and idempotent APIs—combined with mechanisms such as distributed locks and atomic transactions—helps maintain system stability while avoiding duplicate operations and resource exhaustion.
