One entry to global acceleration.
Multiple top-tier CDNs and object storage, fused with smart scheduling and automatic failover, so your site is fast and stable everywhere.
The power of fusion
Several upstream networks combined into one: wider coverage, more capacity.
Visitors always take the best path
A visitor sends a request
Wherever visitors are and whichever carrier they use, requests reach KunYun's smart scheduler first.
Scheduled by region and carrier
The scheduler routes each visitor by carrier and by mainland or overseas line to the upstreams in the policy.
Multiple upstreams online
Each domain runs on several upstreams at once with synchronized settings, ready to switch.
Automatic failover
Every upstream is probed continuously; on failure, traffic moves to healthy upstreams within minutes and back after recovery.
Pick your acceleration
Mainland China
For ICP-filed domains serving mainland visitors, with a line per carrier.
No ICP filing
Accelerate without ICP filing using nodes around mainland China.
Overseas
Global reach by fusing international CDNs.
