You can view the overall bandwidth and network performance for the Beijing region in the table below. Additional notes:
-
Dual‑IPv6 (China Unicom) instances: If you need a China Mobile IPv6 address, run the script provided at
cdn.kuxueyun.com; otherwise, the system assigns only one IPv6 address by default. -
Single‑IPv6 instances: IPv6 addresses are allocated automatically—no manual configuration required.
-
NAT forwarding: For detailed rules and examples, please see the Port Forwarding section in the Help Center.
-
Hardware: Every instance uses high‑performance NVMe SSDs; NAT4 models come with even higher‑spec hardware.
* CM denotes Beijing Mobile, indicating the presence of an additional China Mobile egress. UDP support and mobile entry are not guaranteed services.
Beijing Unicom 9929 Plan — Overview
The 9929 circuit is deeply optimized for overseas traffic, offering a round‑the‑clock, low‑latency experience comparable to China Telecom CN2 and China Mobile CMI2.
Mainland China egress nodes
Guangzhou → Hong Kong — Direct outbound peering with PCCW / NTT (including Cloudflare CDN). If an IP is HKIX‑enabled, true 9929 low‑latency connectivity is possible in both directions.
Shanghai → Japan — Low‑latency links to major carriers such as NTT, SOFTBANK, and IIJ.
Beijing → Germany — Direct paths to most German data centers, cutting latency and boosting throughput.
Shanghai → United States — 9929 peering via carriers with Cogent routes (e.g., RN, CC, and similar providers).
Key benefit
By choosing the 9929 overseas‑optimized circuit, you enjoy consistently high average bandwidth and rock‑solid stability—regardless of moment‑to‑moment latency variations.
