Summary

  • University of Hawaii describes HIX as its exchange for local government, education and research networks. It connects to the separate commercial exchange operated by DRFortress.
  • Public records identify HIX and list exchange participants. They do not measure how much traffic stays in Hawaii or how services would fare during a cable failure.

The university's first contribution was modest: a router and a dedicated access circuit. David Lassner of University of Hawaii's Information Technology Services had proposed the idea in 1994. Networks in Hawaii needed a place to exchange local traffic, without spending their links to the wider internet on a journey between neighbours.

According to the university's history, the proposal drew attention at the first ISOC-Hawaii meeting in mid-1995, and Hawaii Internet Exchange, HIX, began operating shortly afterwards. The original circuit used Frame-Relay, an older networking service. This is the project's beginning, not a description of equipment still in use.

Why put university money into the connection between networks? The university's answer was about the people using them: less delay, lower costs and a better chance of keeping Hawaiian networks connected when a circuit to the mainland failed. Those were the benefits it described, not measured savings or a promise that every local service would survive a cut.

Today the names in its published history make the purpose easier to grasp than a port speed does: education, research and government, with networks including Hawaii Department of Education and US Geological Survey. The university says its technology service manages and funds HIX. Its homepage was last updated in April 2014, so the account explains an institutional commitment rather than certifying present-day performance.

A university exchange, with a commercial neighbour

The division of work became clearer in 2013. According to the university's history, HIX turned its attention to government, education and research, while maintaining a connection to DRFortress's commercial exchange. The two names describe different operations. Their connection is what lets the institutional side meet local provider networks.

The old engineering description is unusually tangible: one router at the Manoa campus, another at DRFortress near Honolulu airport, and a Gigabit Ethernet link between them. That is historical topology, not a claim that the same link speed remains in use today.

Nor did a no-fee peering policy make the whole journey free. The university's joining guidance put the cost of circuits and relevant colocation on participants. It described networks bringing their own registered network number and exchanging routes to Hawaii destinations. The offer was local interconnection, not a promise to carry every participant's traffic around the world at no cost.

DRFortress describes its DRFxchange service as a commercial place for local traffic exchange, with redundant exchange infrastructure and options for bilateral or multilateral peering. These are the operator's service claims. They are not independent proof of a particular latency saving.

One connection is not the whole exchange

The identity is not a mystery. The university explicitly names HIX and its network number, AS19035; ARIN's registration also names Hawaii Internet Exchange. An empty search for an exact exchange name in a different part of a database cannot erase that evidence.

On 21 October 2026, PeeringDB listed one HIX attachment to DRF IX, at 10,000 Mbps, with IPv4 and IPv6 addresses. That is a listed 10 Gbps connection, not HIX's total capacity or the amount of traffic flowing through it. Its December 2019 creation and update timestamps are 82 seconds apart. They tell us about a record, not how quickly somebody installed a port. An old timestamp does not establish that an exchange has been neglected; HIX's network-level record has later updates from 2023.

There are people and institutions behind those rows. The university's legacy network list includes Hawaii Department of Education, State of Hawaii and US Geological Survey among reachable networks. It should not be mistaken for a newly audited membership census. On the commercial side, DRFortress directs readers to DRF IX's public participant page, which showed 34 peers and 40 connections in the October snapshot. Public participant information exists; a live traffic measurement is a different thing.

Local does not mean isolated

Hawaii still needs its ocean connections. Southern Cross describes its North/South system linking Hawaii with Australia, New Zealand, Fiji and the US west coast. BW Digital's account of Hawaiki places Hawaii on that cable's route and dates commercial service to 2018. Neither account establishes HIX's cable contracts or a tested backup path.

The local exchange and the ocean cable answer different needs. One helps networks reach nearby counterparts; the other reaches places that are not nearby at all. HIX's story is not that Hawaii can dispense with the Pacific crossing. It is that not every conversation between Hawaiian networks should need one.

Correction, 21 October 2026: HIX's identity and publicly available participant information have been verified. Earlier claims that its full name was unconfirmed, that participant information was unavailable, or that an unchanged connection record demonstrated abandonment have been withdrawn.
