How we measure
Status is computed from real delivery receipts across every carrier route. A channel in a country is marked Operational when delivery success on the rolling 15-minute window is above 95%, Degraded between 70–95%, and Outage below 70%. Maintenance windows are scheduled and posted in the changelog.
