No latency target will be given for Delivery Receipt Latency since Service Provider can deprioritize Content delivery receipts.

1.3 “Exclusion(s)” means unavailability of the Service for one or more of the following reasons:

Any scheduled maintenance for which Sinch gives prior notice.
Failure of, or congestion experienced in any part of a network outside of where the Service are hosted (e.g. Service Providers or internet);
