What is a CDN, and does my site need one?
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.
Why is UD's China acceleration faster than overseas providers?
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.
Does UD CDN help with ICP filing?
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.
How is UD CDN priced?
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.
How is UD CDN different from Cloudflare / Akamai?
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.
Do I need to change my DNS to use UD CDN?
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.
