A content delivery network (CDN) caches your site on nodes worldwide, letting visitors load from the nearest one — faster and steadier. A millisecond of lag can lose a visitor, especially for finance, gaming, e-commerce and live streaming, where a CDN is close to essential. Run by a Hong Kong telecom operator since 1998, UD CDN offers HKD pricing, Cantonese live support, and CN2 GIA ICP-free acceleration for Mainland visitors — a dependable choice for Hong Kong businesses expanding across Greater China and overseas.
Fast and stable, low cost, more secure — a Hong Kong local telecom team operating since 1998.
Nodes across the globe and Greater China with 300Gb+ bandwidth to spread load; our own platform is simple to use.
Usage-based billing, no contract, no minimum; distributed nodes ease the strain on your origin.
Routing through nodes hides your real IP and lowers DDoS risk, with 24×7 trilingual support.
CN2 GIA direct route, no Mainland filing needed.
Per-GB billing, pay as you go, from HK$0.28 / GB.
No sales call needed — start your trial now.
Local engineering team, 15-min average response.
Different industries · different scaling headaches · one acceleration stack
Overseas customers leave after a one-second wait — conversions and orders lost together
No ICP filing, yet Mainland visitors can barely load the site
When viewership peaks, traffic spikes crush the origin in an instant
A millisecond of latency is enough to lose an order or a match

A CDN caches your content on edge nodes worldwide so visitors connect to the nearest one, cutting latency. It's especially valuable for speed-sensitive sites such as e-commerce, media, SaaS, finance, and gaming, where every 100 ms of delay can cost about 7% in conversions.
UD uses China Telecom's top-priority CN2 GIA lines with nodes near the Mainland (Hong Kong, Shenzhen, Shanghai), keeping average latency under 50 ms. As a Hong Kong ISP, UD peers directly via BGP with all three Mainland carriers.
Either route works. If you must host inside the Mainland, UD offers ICP filing assistance. If not, UD's China CDN runs ICP-free by default, live instantly with no approval wait.
Tiered per-GB billing in HKD, with no monthly fee, no minimum spend, and no long-term contract. Hong Kong is as low as HK$0.28/GB (from HK$0.60/GB, cheaper the more you use), and monthly plans go down to HK$0.20/GB. The first 2,000,000 HTTP requests are free, and you can open a trial account.
UD has been a Hong Kong telecom operator since 1998: HKD pricing, 24/7 Cantonese live support, and CN2 GIA China acceleration without ICP filing. Global providers usually price in USD, support via asynchronous English tickets, and run sparser Mainland nodes.
Just point your domain's CNAME to the UD CDN endpoint; it propagates worldwide within minutes to hours. Setup averages 30 seconds, with our local engineering team supporting you throughout.
