2026-06-24 Rate Limiting for Public Zone Free Edition

Change and Impact

Dear Customers,As the user base of Alibaba Cloud DNS Free Edition has grown rapidly, the total volume of DNS queries handled by the platform has continued to increase. To ensure the stability and availability of our global DNS infrastructure, we are introducing a daily query limit for the Public Zone Free Edition, effective June 24, 2026.What’s Changing1. The Public Zone Free Edition will enforce a per-domain daily query limit:Daily limit per domain: 100,000 queries2. Over-limit behavior: During periods of high traffic or concurrent load, dynamic rate limiting (such as increased response latency or packet drops) may apply to excess queries to protect service stability.ImpactBased on past usage data, most Free Edition users have daily query volumes well below this threshold. No action is required for the majority of users.

Action required

1.Check your usage: Log on to the Alibaba Cloud DNS console to review query volume trends for your Free Edition domains and plan accordingly. Link

2.Upgrade: If any domain exceeds 100,000 daily queries, we recommend upgrading to the Paid Edition for higher quotas, SLA coverage, and seamless migration.Upgrade Guide
