Compute Engine Service Level Agreement (SLA)

Last modified: April 07, 2020 | Previous Versions

During the Term of the agreement under which Google has agreed to provide Google Cloud Platform to Customer (as applicable, the "Agreement"), the Covered Service will provide a Monthly Uptime Percentage to Customer as follows (the "Service Level Objective" or "SLO"):

Covered Service Monthly Uptime Percentage
Instances in Multiple Zones >= 99.99%
A Single Instance >= 99.5%
Load balancing >= 99.99%

If Google does not meet the SLO, and if Customer meets its obligations under this SLA, Customer will be eligible to receive the Financial Credits described below. This SLA states Customer’s sole and exclusive remedy for any failure by Google to meet the SLO. Capitalized terms used in this SLA, but not defined in this SLA, have the meaning set forth in the Agreement. If the Agreement authorizes the resale or supply of Google Cloud Platform under a Google Cloud partner or reseller program, then all references to Customer in this SLA mean Partner or Reseller (as applicable), and any Financial Credit(s) will only apply for impacted Partner or Reseller order(s) under the Agreement.

Definitions

The following definitions apply to the SLA:

  • “Covered Service” means:

    • Instances in Multiple Zones.
    • A Single Instance.
    • Load balancing as part of the Compute Engine Service.
  • “Downtime” means:

    • For virtual machine instances: loss of external connectivity or persistent disk access for the Single Instance or, with respect to Instances in Multiple Zones, all applicable running instances.

    • For load balancing: loss of external connectivity (via the external IP addresses associated with load balancing forwarding rules with all Healthy Backend Instances) due to the failure of Google’s systems.

    • Downtime does not include loss of external connectivity as a result of (i) the Google managed VPN service failing to serve traffic directed to VPN tunnels under that service; that sort of downtime is addressed exclusively in the Cloud VPN SLA; or (ii) Network Service Tiers - Standard Tier failing to serve traffic.

  • “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 for Instances in Multiple Zones and load balancing:

    Monthly Uptime Percentage Percentage of monthly bill for the respective Covered Service in the Region affected which did not meet SLO that will be credited to future monthly bills of Customer
    99.00% - < 99.99% 10%
    95.00% - < 99.00% 25%
    < 95.00% 50%

  • “Financial Credit” means the following for a Single Instance:

    Monthly Uptime Percentage Percentage of monthly bill for a Single Instance in the Region affected which did not meet SLO that will be credited to future monthly bills of Customer
    95.00% - < 99.50% 10%
    90.00% - < 95.00% 25%
    < 90.00% 50%

  • “Healthy Backend Instances” means instances that are responding affirmatively to load balancing health checks.

  • “Instances in Multiple Zones” means virtual machine instances hosted as part of the Compute Engine Service where instances are placed across two or more Zones in the same Region.

  • “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 https://cloud.google.com/compute/docs/regions-zones/, as may be updated by Google from time to time.

  • “Single Instance” means a single virtual machine instance hosted as part of the Compute Engine Service.

  • “Zone” means the applicable zone described at https://cloud.google.com/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 thirty days from the time Customer becomes eligible to receive a Financial Credit. Customer must also provide Google with server log files showing loss of external connectivity errors and the date and time those errors 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 aggregate maximum 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 by 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. As applicable, Customer will only be entitled to Financial Credit for Downtime of a particular virtual machine instance as either a Single Instance or Instances in Multiple Zones, but not both.
