Overview
Kingsoft Cloud was founded in 2012 and is headquartered in Beijing. It is listed on Nasdaq as KC and Hong Kong as 3896. Its CDN portfolio covers static content, downloads and video delivery.
Storage, servers, WAF, media transcoding and AI training or inference are separate cloud services. Select the CDN product and account region first, then check which related services your workload needs.
Network
Mainland and international scope
The mainland CDN describes coverage across China’s major access operators. The English site also offers international cloud services, but cloud data centers are not automatically CDN cache locations.
A complete cache-city list is unconfirmed for this service. Confirm coverage, account eligibility and required domain approvals for your audience, and test delivery from those locations before committing.

Cache and access controls
Configure cache policy, content refresh and prefetch, headers, compression and query-string handling through the console or API. Timestamp-based signed URLs, Referer rules and IP lists control access.
Origins and security
A main and standby origin can be configured. CDN DDoS and CC protection is described separately from the broader cloud WAF portfolio. Bandwidth throttling can redirect or reject traffic after a threshold; propagation delay and possible overshoot mean it is not a strict spending cap.
Logs and media
Access logs and bandwidth, request, status-code and hit-rate statistics are available. The download workflow stores log files by day; confirm freshness and export requirements for your account.
Live and on-demand delivery are supported. Transcoding and other media processing are separate services. Ask separately about code running on CDN viewer requests if your application requires it.
Pricing
Mainland packages
Published packages valid for twelve months include 500 GB for ¥90 and 5 TB for ¥850. A separate package covers 100 million HTTPS requests for ¥360. These terms apply to mainland China usage.
Estimate the right product
Confirm traffic versus bandwidth billing, package eligibility and expiry, request charges and overage rules. International terms may differ. The calculator accepts a confirmed USD quote; convert yuan prices before entering them and do not treat an annual package as a monthly subscription. Storage, origin compute, media processing and security can add separate charges.
Developer tools
The Documentation link opens the CDN-specific hub, including domain configuration, certificates, cache operations, logs and statistics APIs. Use the CDN-specific interfaces for those actions.
Kingsoft maintains a Terraform provider for cloud infrastructure. Check whether the Terraform provider covers the CDN resources you need before planning automation.
When it fits
- Mainland delivery with separately verified account and domain requirements.
- Static, download or video workloads that need cache configuration and signed access.
- Teams already using Kingsoft origins or media services and able to compare their separate charges.
Before you choose
- Mainland packages are prepaid in yuan and have an expiry date; convert the price and match it to your actual usage period.
- AI and broader cloud security are separate products.
- Allow for bandwidth-cap propagation and overshoot. Check CDN Terraform resources before planning automation.
