Neburst S3N-1C1G Hong Kong 163PP/9929/CMIN2 | 55.92 USD/Quarter | 500Mbps | Evening Peak Speed Tests | International Connectivity | Daddy Host Review

Testing the 55 USD Hong Kong plan I won earlier in the Neburst group lottery.

This 55 USD price is actually based on the original 69.9 USD quarterly price plus a limited 20% lottery coupon. Bandwidth is only 500Mbps; if DC switching is implemented later, it should be fairly interesting to play with.

5. Evening Peak Direct Single-Thread Speed Tests (2025-12-21 21:00-23:00)

Very stable. Single-thread speeds on all three networks basically reach 470Mbps+ at best, and latency is also excellent.

The speed-test charts also include data from comparable 1G-port models.

6. International Connectivity

Within Hong Kong it basically saturates 500Mbps both ways, and performance to Japan and Singapore is also good.

Web Latency

bash <(wget -qO- https://raw.githubusercontent.com/danger-dream/network-latency-tester/main/latency.sh)

To TG DC5 it goes through sg.gs and to TG DC4 it goes through Vodafone; both routes are connected by Telegram, so in theory speeds should be faster.

7. Summary

A well-rounded machine with no real weak point. Aside from the smaller bandwidth making speed-test screenshots less impressive, it is more than enough for personal use; the three networks are balanced, performance is stable, and international connectivity is excellent.
