[Landing Node] Triangle Network Hong Kong Broadband HKBN DIA | New Kaze Site | v4/v6 International Connectivity | Review

Testing Kaze's new HKBN DIA product on the new site. The first 200 machines are upgraded to 1000Mbps for free, so let's see how it performs after the upgrade.

HKBN DIA means Dedicated Internet Access purchased from HKBN.

Users who bought v6-only models can also use this as a reference for international connectivity.

🎬IP quality

Although this is HKBN DIA, the IP is still anycast. Unlocking is currently quite good.

IPv4	IPv6

🌐Network quality

Mainland return is limited to 20Mbps. It is fine for small-bandwidth needs, but v6 Mobile latency is too high.
It looks like outbound from Hong Kong is limited to 50Mbps.

5. Evening peak proxy speed tests

Telecom and Unicom can basically fill the 20Mbps Mainland China bandwidth, while Mobile cannot even fill that.

6. International connectivity - IPv4

Intra-Hong Kong single-thread tests can basically reach 900Mbps+. Asia-Pacific speeds are also decent, with a small number at 50Mbps. Europe and America are weaker, with many nodes only around 50Mbps.

[Test records]

7. International connectivity - IPv6

Overall, v6 is much worse than v4. Intra-Hong Kong tests can also approach full speed, but are lower than v4. Hong Kong to HGC v6 latency is too high. Latency to Japan is okay, but speed cannot get going.

[Test records]

8. Summary

For international connectivity, local Hong Kong and Asia-Pacific are barely acceptable, but Europe and America are poor. Outbound speed from Hong Kong may be limited to 50Mbps. However, most major websites have CDNs in Hong Kong, so it works as a landing node; after all, the IP is HKBN. It is just not very suitable for international transit.

For direct connection, it is a small pipe. Telecom and Unicom can almost fill 20Mbps, while Mobile is more painful.
