Service Availability (SLA)
MariaDB SkySQL customers should assess the availability requirements of their application and choose an appropriate service tier to meet their objectives. MariaDB SkySQL customers are on the Foundation Tier unless they have specifically purchased and paid for Power Tier service.
SkySQL Foundation Tier
SkySQL Power Tier
Service Downtime is measured at each SkySQL database endpoint as the total number of full minutes, outside of scheduled downtime for maintenance and upgrades, where continuous attempts to establish a connection within the minute fail as reflected in minute-by-minute logs.
Monthly Uptime Percentage
Monthly Uptime Percentage is calculated on a per-billing-month basis as the total number of minutes in a month, minus the number of minutes of measured Service Downtime within the month, divided by the number of minutes in that month. When a service is deployed for only part of a month, it is assumed to be 100% available for the portion of the month that it is not deployed.
Service Credit is the percentage of the total fees paid by you for a given SkySQL service during the month in which the downtime occurred to be credited if MariaDB approves your claim. The percentage used in calculating Service Credit is dependent on whether the customer is on Foundation Tier or Power Tier, and is dependent on the calculated Monthly Uptime Percentage.
Monthly Uptime Percentage
Less than 99.95%, but greater than or equal to 99.0%
Less than 99.0%
Less than 99.995%, but greater than or equal to 99.0%
Less than 99.0%
MariaDB will grant and process claims, provided the customer has satisfied its Customer Obligations and that none of the Exclusions listed apply to the claim. Service Credits will be issued only upon request within 60 days of the end of the billing period of the month of impact to service availability, and upon confirmation of outage. Service Credits will be issued in the form of a monetary credit applied to future use of the service that experienced the Service Downtime. Service Credits will not be applied to fees for any other SkySQL instance.
The aggregate maximum number of Service Credits to be issued by MariaDB to customers for any and all Service Downtime that occurs in a single billing month will not exceed 50% of the amount due from the customer for the covered service for the applicable month.
A customer will forfeit their right to receive a Service Credit unless they:
Log a support ticket with MariaDB Support within 60 minutes of first becoming aware of an event that impacts service availability.
Submit a claim and all required information by the end of the month immediately following the month when the Service Downtime occurred.
Submit necessary information for MariaDB to validate the claim, including:
Provide reasonable assistance to MariaDB in investigating the cause of the Service Downtime and investigating your claim.
The Performance Standard does not apply to single instance SkySQL service configuration or services in Technical Preview. Customers requiring High Availability should deploy instead in production-ready multi-node service configuration.
See "Choose a SkySQL Release" for information on SkySQL services in Technical Preview.
Impact to service availability caused by availability or performance of cloud services used to operate MariaDB SkySQL is excluded. This includes any such outages in Amazon Web Services (AWS) and Amazon Elastic Kubernetes Service (EKS), and Google Cloud Platform (GCP) and Google Kubernetes Engine (GKE).
Impact to service availability caused by blocking of network traffic by ISPs, network providers, governments, or third parties is excluded.
Impact to your use of service based on factors outside MariaDB SkySQL are excluded. This includes periods of downtime for your applications.
Only impacts to service availability detected at point of measurement are subject when determining the uptime percentage. Service availability impacts measured through any other means, such as application instrumentation, are excluded except as also measured as Service Downtime by MariaDB.
Impact to your ability to access or use the MariaDB SkySQL portal, an interface provided to manage services, is excluded. This includes any component and content linked from the MariaDB SkySQL portal, including Documentation, the Customer Support portal, Monitoring, and Workload Analysis. These components operate independently from database services and do not impact database availability.
Impact to service availability caused by usage of system resources, such as problems caused by excessive workload consumption of CPU, disk I/O, disk capacity, memory, and other system resources, are excluded.
Clients and connectors
Impact to service availability caused by the use of unsupported third-party clients and connectors is excluded.
The Performance Standard applies only to paying MariaDB SkySQL customers who are paid-in-full. All other MariaDB SkySQL customers, including those not paid-in-full and those customers participating in a free or credited service trial, are excluded.
When a customer directs that MariaDB conduct a maintenance operation on a service, any resulting impact to service availability is excluded.
When a customer approves MariaDB-recommended maintenance on a service, any resulting impact to service availability is excluded.
When a customer initiates changes to their SkySQL services, e.g., via access to the database or via the SkySQL portal, any resulting impact to service availability is excluded.
Availability of services during initial provisioning, e.g., before a service becomes online, healthy, and available, is excluded.
