What exactly did you describe in the scenario of external service unavailability?

In the scenario of external service unavailability, I describe:

• Conditions under which the service becomes unavailable (e.g., timeouts, network errors).
• How the system should respond: retries, switching to a backup service, returning an error to the user.
• Time frames and the number of retry attempts.
• Logging and notifications for incident monitoring.
• Impact on business processes and ways to minimize damage.

For example, if an external API does not respond for more than 5 seconds, the system makes 3 retry requests with exponential backoff, then switches to cached data and sends an alert to the support team.
