Cloud NAT Service Level Agreement (SLA)

The following definitions apply to the SLA:

• "Covered Service" means Cloud NAT (Network Address Translation).
• "Downtime" means loss of external connectivity for the NAT IP address(es) of a NAT gateway for a Region due to failure of such NAT gateway in more than one Zone. Downtime does not include loss of external connectivity as a result of:

(i) a single-Zone failure;

(ii) IP address or port exhaustion of customer-managed IP address pools for the NAT gateway;

(iii) reaching applicable quota limits; or

(iv) failure of another Google service (such as a Google Compute Engine instance) running behind the NAT gateway, which downtime is addressed exclusively in the applicable SLA for that service, if any.

• "Downtime Period" means a period of one or more consecutive minutes of Downtime. Partial minutes or intermittent Downtime for a period of less than one minute will not be counted towards any Downtime Periods.
• "Financial Credit" means the following:

• "Monthly Uptime Percentage" means total number of minutes in a month, minus the number of minutes of Downtime suffered from all Downtime Periods in a month, divided by the total number of minutes in a month.
• "Region" means the applicable region described at /compute/docs/regions-zones/, as may be updated by Google from time to time.
• "Zone" means the applicable zone described at /compute/docs/regions-zones/, as may be updated by Google from time to time.

Customer Must Request Financial Credit

In order to receive any of the Financial Credits described above, Customer must notify Google technical support within 30 days from the time Customer becomes eligible to receive a Financial Credit. Customer must also provide Google with log files showing loss of external connectivity errors and the date and time they occurred. If Customer does not comply with these requirements, Customer will forfeit its right to receive a Financial Credit. If a dispute arises with respect to this SLA, Google will make a determination in good faith based on its system logs, monitoring reports, configuration records, and other available information, which Google will make available for auditing by Customer at Customer's request.

Maximum Financial Credit

The maximum aggregate number of Financial Credits to be issued by Google to Customer for any and all Downtime Periods that occur in a single billing month will not exceed 50% of the amount due from Customer for the Covered Service for the applicable month. Financial Credits will be made in the form of a monetary credit applied to future use of the Service and will be applied within 60 days after the Financial Credit was requested.

SLA Exclusions

The SLA does not apply to any (a) features designated pre-general availability (unless otherwise set forth in the associated Documentation), (b) features excluded from the SLA (in the associated documentation), or (c) errors: (i) caused by factors outside of Google's reasonable control; (ii) that resulted from Customer's software or hardware or third party software or hardware, or both; (iii) that resulted from abuses or other behaviors that violate the Agreement; or (iv) that resulted from quotas applied by the system and/or listed in the Admin Console.
