Alibaba Cloud DNS:Global Traffic Management 3.0 upgrade instructions

Last Updated:Aug 21, 2025

Overview

To simplify user configuration, the new version elevates instance-level configurations to user-level configurations. IPAM pools and health checks are no longer attached to individual instances but are configured globally and can be referenced by all GTM domain instances. Additionally, health checks support template configurations with built-in system templates, allowing you to use them immediately.

Release content

Optimization type

Optimization content

Configuration optimization

  • Graphical orchestration configuration: Introduces graphical orchestration capabilities, making GTM configuration and monitoring more intuitive and convenient.

Scheduling optimization

  • Support for health detection templates: Supports comprehensive determination of service endpoint health status through multiple protocols, ensuring precise and efficient service availability monitoring.

  • Extended load balancing policy: Expands and supports flexible combinations of various load balancing policies, better adapting to complex and changing scheduling scenarios.

  • Multiple line type combinations: Supports combinations of carrier lines and regional lines to meet fine-grained scheduling requirements in different network environments.

  • Batch traffic shifting escape mechanism: In failure scenarios, unified batch traffic shifting at data center level or across multiple applications can be achieved, ensuring business continuity and stability.

Ultimate disaster recovery

  • Cloud/edge heterogeneous disaster recovery: Builds a heterogeneous GTM disaster recovery plan between cloud and edge, providing local data and service backup to achieve extremely stable DNS parsing services.

Operations optimization

  • Global/custom alarm settings: All instances support unified global alarm configuration settings, while also supporting custom alarm configuration settings for individual instances.

  • Status visualization: GTM access domains, IPAM pools, address service availability status, enabled status, and health detection status are displayed, helping customers quickly identify service availability.

Network-wide failback time = fault switching time + network-wide effective time

With health check interval set to 1 minute, TTL to 60 seconds, and consecutive failure count to 2, GTM can accurately detect failures and switch in about 3 minutes. After fault switching, theoretically, it can take effect across the network in about 60 seconds, but the actual situation depends on the cache setting time of carriers across the country.

With health check interval set to 15 seconds, TTL to 1 second, and consecutive failure count to 2, GTM can accurately detect failures and switch in about 1 minute. After fault switching, theoretically, it can take effect across the network in about 1 second, but the actual situation depends on the cache setting time of carriers across the country.

How to upgrade from old GTM to GTM 3.0

If you want to use the new version, you can purchase it and configure it in the new version, then go to DNS settings to point your subdomain to the CNAME access domain provided by the new GTM. For more information, see How to smoothly upgrade from the old version of GTM to GTM 3.0?

Pricing

The purchase method and pricing of GTM 3.0 are completely consistent with the currently running Global Traffic Management instances. Version upgrades will not affect the cost of GTM instances in use. For specific pricing information, see Product Billing.
