CDN (Content Delivery Network) is a network system that can accelerate loading speed for a website.
Normally when a user accesses a website, he has to connect to the website origin server. The greater the distance between server and end users, the longer the loading speed. It is because the contents must travel around the world before appearing on the user’s screen.
CDN can cache website contents in nodes in many locations, and thus build a geographically distributed network which allow shorter distance between the proxy servers and end users. Users can retrieve contents from the nearest node when accessing a website. The shortened distance allows user to enjoy a speedy and stable browsing experience.
A content delivery network is a ring of cache servers around the world that keep copies of your images, scripts, and pages. Visitors download those files from the closest node instead of pulling every byte from one distant origin, which cuts round-trip time, smooths spikes in traffic, and helps sites feel faster in Hong Kong, Mainland China, and overseas markets alike.
Website is now the cornerstone of many corporations. However, demand for network speed also increased greatly in the past few years. Even delays of milliseconds in website response time will lead to unexpected loss. According to previous statistics, the conversion rate to a webpage dropped by 7% for every 100 milliseconds of delay of response time.
If your website has a lot of static contents, or if speed and stability is very important for your business, such as finance, online gaming, retail and streaming, you would need our CDN service.
Hosting a website in China can be much more complicated than you can expect. Not to mention the “Great Firewall of China”, the Internet censorship which greatly increase latency.
UD’s China Routing CDN uses CDN nodes strategically located in the surrounding area of China. Our smart DNS system chooses the fastest route while CN2 network is used for maximum delivery speed to mainland users.

Through diversifying traffic to different local nodes, the load to the origin server will be greatly reduced, saving bandwidth cost while achieving better result.
In most cases, your WordPress hosting company serves your website from only a single location which means all your website audience will access to the same server. If your website is popular or if there are online promotions which drive high traffic to the website, all user requests will drag down your website. During peak traffic hours, it can even crash the server which will make your site temporarily unavailable.
UD CDN is optimized for WordPress. Numerous UD nodes are strategically located in major continents and countries, creating a robust network with comprehensive coverage. Together with 300Gb+ International bandwidth, stability can be maximized.

A CDN is a geographically distributed network of cache nodes that store copies of your website content closer to visitors. Instead of every request travelling to a single origin server, users fetch static assets from a nearby edge node, which reduces latency and improves stability during traffic spikes.
Modern websites underpin sales, support, and brand trust. Small delays add up: studies have linked slower response times to lower conversion rates. CDN helps static-heavy sites and latency-sensitive sectors such as finance, gaming, retail, and streaming stay fast and resilient.
Mainland China access often involves extra routing and filtering. UD’s China Routing CDN uses nodes around the region with smart DNS and CN2-class connectivity options to improve delivery speed and predictability for mainland users compared with a single overseas origin.
For global audiences you want broad edge coverage and ample backbone capacity. UD Global CDN places content near users across major regions and pairs that with large international bandwidth so pages, APIs, and downloads stay responsive for visitors worldwide.
You can start with a trial account. After the trial, usage is billed on a transparent pay-as-you-go basis from actual traffic, without long lock-ins or hidden minimums. Offloading bytes to edges also lowers origin bandwidth costs.
Yes. Typical WordPress hosting serves all visitors from one region; viral traffic or campaigns can overload that origin. UD CDN caches static assets at the edge, spreads load across POPs, and supports SSL and cache rules so WordPress stays fast under peak demand.
