Advantages and features of UCDN

Security and Stability

UCDN ensures secure file transmission with strong networks and protection against DDoS and CC attacks. SurferCloud offers 24/7 support for uninterrupted website operation. It also supports automatic failover to backup origins and reduces bandwidth usage with origin merging during high traffic.

Superior Performance

UCDN delivers excellent acceleration performance, reliably supporting the access and download of large volumes of images, audio, video, and other files, while easily handling high-concurrency access from a massive number of users.

Seamless Cloud Storage Integration

Integrated with object storage US3, UCDN solves the challenges of storing and distributing massive amounts of data. It supports storing origin data in US3, with elastic scaling on demand, enabling faster and more convenient content distribution while reducing costs.

Multiple Use Cases

Small File Acceleratio: Speeds up static files like images, .html, .js, .css, and more.

Large File Download Acceleration: Enhances downloads for game installs and updates, including .exe, .apk, .zip, and large files, with compression and range support.

Audio & Video Streaming: Accelerates streaming of files like .m3u8, .mp4, .flv, .avi, .hls, and supports video seeking.

Monitoring and Data Analysis

Provides minute-level bandwidth, request count data, and monitoring data by province and ISP. This helps analyze client behavior and business performance, offering valuable insights for improving service quality.

User-Friendly and Open API

Supports custom features like anti-hotlinking, cache policies, and HTTP response headers. The open API allows developers to easily access services such as activation, content refresh, monitoring data retrieval, and download logs.

Frequently asked questions

• What is SurferCloud UCDN?

  UCDN (SurferCloud Content Delivery Network) can distribute the accelerated contents of users to over 200 service nodes and then carry out intelligent scheduling and buffering and calculate the nearest access nodes to provide optimized and accelerated networking experiences for users.

• What is the distribution of SurferCloud CDN nodes?

  SurferCloud CDN has a wide global distribution, with service nodes across multiple regions, including Asia-Pacific (APAC-1, APAC-2, APAC-3), North America, Europe, Middle East & Africa, and South America.

• What security protection strategies does UCDN offer?

  SurferCloud's UCDN employs multiple layers of security measures, including Referer and User-Agent verification, IP blacklists and whitelists, and timestamp encryption to prevent hotlinking, among others. These measures help block illegal requests, preventing server resource exhaustion and increased business costs. UCDN can also integrate with the DDoS protection product to defend against various network and transport layer DDoS attacks. Additionally, with UMON resource monitoring, it automatically detects service anomalies.

• What is the pricing structure for UCDN?

  The pricing is tiered based on the size of the CDN traffic package you purchase—the larger the traffic, the lower the unit price. Additionally, different regions have different pricing, allowing users to select the region that suits their needs when purchasing traffic packages. This model provides flexibility and scalability for global content delivery.

• Why do some CDN providers charge extra for HTTPS acceleration?

  Many businesses face additional fees for CDN acceleration services when using HTTPS, as enabling HTTPS increases the computational load for encryption and decryption. CDN service providers typically charge extra fees based on traffic and encryption requirements. These costs can be particularly significant in high-traffic or encryption-intensive scenarios, increasing operational expenses for businesses. To help customers reduce costs and improve efficiency, SurferCloud has chosen to absorb these additional CDN acceleration costs, providing businesses with a more efficient and cost-effective service. This allows them to enjoy secure acceleration while minimizing unnecessary expenses.

• What billing models does UCDN support?

  UCDN supports a prepaid model, requiring the purchase of traffic packages in advance, with a validity period of 1 year.
