JDIDC has recently launched its US Zone 6 CUVIP DDoS-Protected VPS series, featuring optimized China Unicom AS4837 return routes across all three major Chinese ISPs and 30Gbps DDoS protection. For websites, gaming services, and other projects targeting users in mainland China, network quality and DDoS mitigation capabilities are often more important than raw hardware performance.
The VPS tested in this review comes from the JDIDC US CUVIP DDoS-Protected VPS lineup. Although the test machine is configured above the entry-level plan, all packages include a 300Mbps network port and support both Linux and Windows operating systems, including Windows 7, Windows 10, Windows Server 2003, 2008, 2012, 2016, and 2019.

Hardware Performance Test
According to the benchmark results, the server is powered by:
- Intel Xeon E5-2699 v4 Processor
- 2.20GHz Base Frequency
- KVM Virtualization
The test VPS detected approximately 3950MB of available memory, with swap disabled by default.
Storage performance:
- SSD Storage
- Average Read/Write Speed Around 877MB/s
For website hosting, database workloads, download relay services, and small-to-medium business applications, this level of disk performance is more than sufficient.
In addition, BBR acceleration was manually enabled during testing to further improve network transmission efficiency.
Network Bandwidth Performance
Download Speed
Multiple domestic and international speed test nodes were able to fully utilize the 300Mbps bandwidth allocation.
Upload Speed
Most testing nodes consistently delivered:
220Mbps to 240Mbps
Overall bandwidth resources were plentiful, with no obvious throttling observed.
This level of performance is more than adequate for website hosting, file transfers, and video-related services.
Latency Test Within China
Testing results showed:
Average latency to mainland China: approximately 180ms
This is typical performance for a US West Coast-based data center.
Considering the additional DDoS protection capabilities, the latency results are quite reasonable.

During extended testing periods, almost no noticeable packet loss was observed on either domestic or international routes.
Overall network stability is excellent.
IP Type and Streaming Unlock Test
The IP classification results are quite interesting.
Several IP databases identified the address as:
- Seychelles-Based IP
- Single-ISP Network
- Residential Broadband IP in Some Databases
- Commercial IP in Other Databases
This is a relatively uncommon IP type.
