Test a controlled connection change and its recovery. Record new-request success separately from the behavior of an existing call, VPN or transfer. Use seconds for durations.

Gateway / firmware: _______________________ Primary / backup services: _______________________
Client / application / version: _______________________ Date / timezone: _______________________
Failure method and restoration procedure: __________________________________________________
Acceptance target — new request: __________ seconds; existing-session interruption: __________ seconds
Before testing: use equipment you control; save settings; choose a maintenance window; verify both paths independently; follow the gateway’s documented method. A cable disconnect and an upstream outage are different tests.
| Run / event | Event time | New request works at / elapsed s | Existing-session interruption s / manual action | Actual path and result |

Observed range / pass or fail against the stated target: ______________________________________________
Common dependencies, unknowns and follow-up changes: ___________________________________________
An existing session that reconnects after 23 seconds and a new request that works after 8 seconds are different outcomes. Record actual measurements; the example is fictional. Retest after firmware, provider or application changes.
