Posted on: Apr 3, 2025

Today, AWS announces an updated service level agreement (SLA) for HAQM Neptune, increasing the Monthly Uptime Percentage for Multi-AZ DB Instance, Multi-AZ DB Cluster, and Multi-AZ Graph from 99.90% to 99.99%. This enhancement reflects AWS’s continued commitment to providing a highly available and reliable graph database service for your mission-critical applications.

With this new SLA, AWS will use commercially reasonable efforts to make each HAQM Neptune’s Multi-AZ DB Instance, Multi-AZ DB Cluster, and Multi-AZ Graph available with a Monthly Uptime Percentage, during any monthly billing cycle, of at least 99.99%. If Neptune does not meet this Service Commitment, customers will be eligible for Service Credits as outlined in the HAQM Neptune SLA.

This improved SLA is now available in all AWS regions where HAQM Neptune is offered. For more details, visit the AWS Global Region Table and learn more about Neptune on our product page, developer resources, and documentation.
