According to a product announcement released by Alibaba Cloud, the free version of Alibaba Cloud DNS service will start to limit the speed from June 24, 2026. The daily resolution limit for domain names using the free version of Cloud DNS is 100,000 times. If the number exceeds 100,000 times, the cloud resolution system may take dynamic speed limiting measures on the excess part, such as request response delays or packet loss.
Of course, if the domain name request volume itself is large, users need to consider migrating to other public network authoritative resolutions or purchasing the paid version of Alibaba Cloud Cloud Resolution DNS. The paid version provides higher resolution quotas and SLA guarantees. For corporate websites or services with high concurrency and high traffic, you can consider purchasing the paid version of DNS resolution services.
Why does Alibaba Cloud limit the speed of the free version:
Alibaba Cloud stated that with the rapid growth in the number of users of the free version of Cloud DNS public network authoritative resolution, the total amount of resolutions carried by the Alibaba Cloud platform is constantly rising. Therefore, in order to ensure the overall stability and high availability of global resolution links and avoid affecting the normal business of users due to local traffic increases or abnormal queries, it is necessary to control the extremely large traffic requests of the Cloud DNS free version.
According to Alibaba Cloud statistics, the average daily resolution volume of most free users is well below the 100,000 threshold, so most users can continue to use Alibaba Cloud DNS without switching to other platforms or paying for the paid version of Cloud DNS.

Is there any free DNS resolution service with no speed limit:
It is crucial for webmasters and enterprises to use stable and reliable DNS resolution services. If you are worried that continuing to use Alibaba Cloud's DNS service may cause over-limit problems, you can also migrate the domain name DNS to other platforms. The DNS records themselves can be bound at will and there is no need to move the domain name out of Alibaba Cloud to other platforms.
The most widely used DNS service is Cloudflare. For example, almost all domain names and services of Bluepoint.com are hosted on Cloudflare. Cloudflare DNS resolution takes effect quickly and with high stability. For most websites, Cloudflare DNS can meet the usage requirements.
But if the website requires partition resolution, it is not appropriate to use Cloudflare. Partition resolution is usually a paid service. However, Tencent Cloud DNSPOD free version also provides basic partition resolution, which can be resolved to different locations according to different operators. This should also satisfy some webmasters who have needs for partition resolution.
Tencent Cloud DNSPOD free version supports partition resolution including: by operator (Telecom, China Mobile, China Unicom, other operators), by region (domestic or overseas), search engine dedicated lines, custom lines, etc.
