With all commercially reasonable efforts, and counting all parameters that Passendo can control, Passendo will ensure that the availability of our services will be 99.95% as seen over a rolling 30 (thirty) day window.

The same availability guarantee is made for our Management Platform, but only within business hours. Monthly Uptime Percentage of 99.95% means that we guarantee you will experience no more than 21.56 min/month of Unavailability.

If we do not meet this Service Commitment, the Publisher will be eligible to receive a Service Credit as defined below.

This does not include Service Maintenance as defined otherwise in this contract.

2) Definitions

These ads should be fetched fully and wholly within a defined time period, as otherwise defined in this agreement.
