AboutUD CDN
A content delivery network built for Hong Kong businesses.
UD CDN caches your sites, apps, APIs, and video on edge nodes in Hong Kong, around the Mainland, and worldwide, backed by CN2 GIA lines and a 24/7 local team.
Infrastructure across
three tiers
Hong Kong, the Mainland, and worldwide: three PoP tiers back each other up, routing every user to the nearest node.
Local data centres and backbone
Five major Hong Kong data-centre nodes, each with over 100Gb of dedicated local bandwidth and full mutual redundancy, so local users are served from the nearest node with millisecond latency.
Mainland dedicated lines
China Telecom CN2 GIA lines, the highest-priority access into the Mainland, backed by all three carriers. Mainland users connect directly via Hong Kong nodes, with no ICP filing.
Worldwide node coverage
Edge nodes across major markets in Asia, Europe, and the Americas, backed by 300Gb+ of international egress. During major campaigns or global traffic spikes, load is distributed automatically to keep performance stable.
Local team
service and operating standards
UD CDN is run end-to-end by a local Hong Kong engineering team: from access and routing to incident response, all handled by one team.
Local Hong Kong engineering team
Technical design, customer support, and incident response are all handled by the local team, with no tickets bounced across time zones. Email, phone, and live chat are staffed around the clock by real people.
Deep local network experience
The team has spent years deploying and tuning nodes across Hong Kong, the cross-border Mainland, and global markets, with deep expertise in CN2 GIA access, HKIX peering, edge security, and multi-protocol streaming. Every CDN solution runs on a single engineering stack, with consistent deployment and support standards.
