-This article outlines the accelerated logs feature and guides you through enabling or disabling this feature for the Azure Database for MySQL service based on the Business Critical service tier.
+Azure Database for MySQL - Flexible Server introduces the Accelerated Logs feature, now generally available for servers utilizing the [Business Critical service tier](./concepts-service-tiers-storage.md). This documentation outlines the steps to enable or disable the accelerated logs feature, providing you with the flexibility to optimize your server's performance as needed.  
 
 > [!IMPORTANT]  
-> The accelerated logs feature is currently in and subject to [limitations](#limitations) and ongoing development. This feature is only available for servers based on the Business -Critical service tier. We recommend using it in non-production environments, such as development, testing, or quality assurance, to evaluate its performance and suitability for your specific use cases.
+> The accelerated logs feature will be available for Business-Critical servers created after May 20th, 2024. For servers already under the Business-Critical service tier, this feature can be enabled following the upcoming maintenance window. Please visit the “Maintenance” section on our portal for details about the next maintenance schedule. For any further queries or assistance, please create a [support ticket](https://azure.microsoft.com/support/create-ticket/)
 
 ## Introduction
 
 The accelerated logs feature is designed to significantly boost performance for users of the Business Critical service tier in Azure Database for MySQL flexible server. It substantially enhances performance by optimizing transactional log-related operations. Enabling this feature allows a server to automatically store transactional logs on faster storage to enhance server throughput without incurring any extra cost.
 
-Database servers with mission-critical workloads demand robust performance, requiring high throughput, and substantial IOPS. However, these databases can also be sensitive to latency fluctuations in server transaction commit times. The accelerated logs feature is designed to address these challenges by optimizing the placement of transactional logs on high-performance storage. Separating transaction log operations from database queries and data updates results in significant improvement in database transaction commit latency times.
+Database servers with mission-critical workloads demand robust performance, requiring high throughput, and substantial IOPS (I/O per second). However, these databases can also be sensitive to latency fluctuations in server transaction commit times. The accelerated logs feature is designed to address these challenges by optimizing the placement of transactional logs on high-performance storage. Separating transaction log operations from database queries and data updates results in significant improvement in database transaction commit latency times.
 
 ### Key benefits
 
 - **Enhanced throughput:** Experience up to 2x increased query throughput in high concurrency scenarios, resulting in faster query execution. This improvement also comes with reduced latency, reducing latency by up to 50%, for enhanced performance.
 - **Cost efficiency**: Accelerated logs provide enhanced performance at no extra expense, offering a cost-effective solution for mission-critical workloads.
 - **Enhanced scalability:** Accelerated logs can accommodate growing workloads, making them ideal for applications that need to scale easily while maintaining high performance. Applications and services on the Business Critical service tier benefit from more responsive interactions and reduced query wait times.
 
+> [!Note]  
+> If [Zone Redundant HA](./concepts-high-availability.md) is enabled for your server, additonal latency due to the cross zonal copy of data is anticipated. We recommend users to conduct their own benchmark tests for accurate performance assessment.
+
+## Limitations
+
+- The accelerated logs feature can't be enabled on servers that have [Customer Managed Keys](./concepts-customer-managed-key.md)  (CMK) enabled.
+
+- The Accelerated logs feature is currently available only in specific regions. [Learn more about supported regions](#regions).
+
+- After the accelerated logs feature is activated, any previously configured value for the ["binlog_expire_seconds"](https://dev.mysql.com/doc/refman/8.0/en/replication-options-binary-log.html#sysvar_binlog_expire_logs_seconds) server parameter will be disregarded and not considered.
