9. FAQ

Q1: Is VMISS Osaka IIJ VPS good for website hosting?
Yes, it is suitable for lightweight websites, especially those targeting users in China. Direct routing across all carriers ensures stable performance, but higher-tier plans are recommended for production use.

Q2: Why is it not suitable for relay usage?
Because latency to other Asia-Pacific nodes such as Tokyo, Hong Kong, and Singapore is relatively high, and the routing is not optimized for proxy forwarding scenarios.

Q3: How is streaming performance?
Streaming unlock behavior is unusual: Netflix and Disney+ identify the IP as Canada region. It works but is not consistent for strict regional requirements.

Q4: Difference between Osaka IIJ and Tokyo IIJ?
The routing structure is similar, but Osaka may show slightly higher latency in some regions while offering slightly better disk performance. Users can choose based on specific needs.

Overall, the VMISS Osaka IIJ VPS is a highly cost-effective, practical VPS solution:

• Strong network stability (direct routing + low packet loss)
• Excellent bandwidth performance (400Mbps+)
• Outstanding video streaming experience

However, it also has clear limitations:

• Poor IP quality
• Not suitable for relay/proxy usage
• Unstable streaming geo-identification

👉 One-line summary:
If you only need it for video streaming or lightweight website hosting, this Osaka IIJ VPS is a great choice. But if you require high-quality IP or relay performance, consider other alternatives.
