The Service Commitment does not apply to any unavailability, suspension or termination of Amazon S3, or any other Amazon S3 performance issues: (i) that result from a suspension described in Section 6.1 of the AWS Agreement; (ii) caused by factors outside of our reasonable control, including any force majeure event or Internet access or related problems beyond the demarcation point of Amazon S3; (iii) that result from any actions or inactions of you or any third party; (iv) that result from your equipment, software or other technology and/or third party equipment, software or other technology (other than third party equipment within our direct control); or (v) arising from our suspension and termination of your right to use Amazon S3 in accordance with the AWS Agreement (collectively, the “Amazon S3 SLA Exclusions”). If availability is impacted by factors other than those used in our calculation of the Error Rate, then we may issue a Service Credit considering such factors at our discretion.
