Summary

  • The Philippine Open Internet Exchange (PhOpenIX) was launched on 24 January 2007 and has been established, managed and operated by the Department of Science and Technology – Advanced Science and Technology Institute (DOST-ASTI) since then (DOST-ASTI release).
  • Administrative Order No. 39, s. 2013 promotes use of the official Government Internet Protocol Exchange Facility, through which all government agencies are mandated to exchange data traffic with other agencies and external stakeholders (policy source).
  • DOST-ASTI's then Acting Director, Dr. Joel Joseph Marciano, Jr., said the Information and Communications Technology Office of DOST had designated PhOpenIX the official government internet protocol exchange, with the successor Department of Information and Communications Technology supporting its growth (DOST-ASTI release).
  • A PeeringDB-derived snapshot with a last sync of September 2026 records 47 members: 39 registered in the Philippines, four in the United States, two in Hong Kong and one in Japan; 31 Cable/DSL/ISP networks, six NSPs, three educational or research networks, one non-profit and five unknown; and 41 of 47 members using RPKI (IXP data page, data sourcing).
  • The same snapshot bounds the claim: the country list and the network-type list each account for 46 of the 47 members, and no port counts, traffic volumes or prices are published, so the order's effect on what Filipinos pay for connectivity cannot be read from these figures.

A nineteen-year-old institutional exchange

Internet exchange points are unglamorous infrastructure. They are the switches where networks hand each other domestic traffic instead of hauling it across an ocean and back. When they work, they are invisible; when they are missing or captured, the cost shows up in latency, in transit bills and in how much of a country's own traffic leaves the country before returning.

The Philippines has an unusual version of that infrastructure. PhOpenIX was launched on 24 January 2007, and DOST-ASTI has established, managed and operated it since then, according to the institute's own account of the exchange (DOST-ASTI release).

That is a long run for a state-operated exchange in a market where the largest carriers also run their own interconnection facilities. The operating model is stated plainly: PhOpenIX operates on a non-profit membership basis and acts as a special carrier-neutral exchange for the public interest (model description). Carrier-neutral means the venue does not belong to a competing access network, which matters when two or three vertically integrated carriers control most last-mile connections. Non-profit means the exchange is not a margin centre; ports and peering are priced to cover operation rather than to extract rent from participants who have few alternatives.

The policy lever: an administrative order and a designation

The distinguishing feature of PhOpenIX is not its port count. It is the instrument behind it. Administrative Order No. 39, s. 2013 promotes the use of the official Government Internet Protocol Exchange Facility, through which all government agencies are mandated to exchange data traffic with other agencies and external stakeholders (policy source).

A mandate of that kind creates demand that does not have to be negotiated network by network. Government agencies, state universities, hospitals and local government units are not free to route around it; if they must exchange traffic through the designated facility, networks that want that traffic must connect to the same place.

Institutional recognition followed. At a ceremonial turn-over of equipment for PhOpenIX hosted by the Department of Information and Communications Technology and DOST-ASTI, DOST-ASTI's then Acting Director, Dr. Joel Joseph Marciano, Jr., stated that the Information and Communications Technology Office of DOST had designated PhOpenIX as the official government internet protocol exchange, and that its successor, the Department of Information and Communications Technology, had given full support to the exchange's growth (DOST-ASTI release).

Two cautions belong with that account. The retrieved record does not date the ceremonial turn-over, and it does not establish whether the title "Acting Director" was current before or after the event. It also does not establish whether the Government Internet Protocol Exchange Facility named in the administrative order is PhOpenIX itself or a separate facility that PhOpenIX serves. Readers should treat the order and the designation as related instruments of the same policy direction, not as a single dated decision chain.

The September 2026 snapshot

The clearest current measurement of the exchange is a PeeringDB-derived data page whose last synchronisation is labelled September 2026 (IXP data page). It records 47 members. Countries of registration break down as the Philippines 39, the United States of America four, Hong Kong two and Japan one. Network types break down as Cable/DSL/ISP 31, NSP six, Unknown five, Educational/Research three and Non-Profit one. Members using RPKI: 41 of 47.

Read as shares, 39 of 47 members — about 83% — are registered in the Philippines, and 41 of 47 — about 87% — sign their routing announcements with Resource Public Key Infrastructure certificates. The membership is dominated by access networks: the 31 Cable/DSL/ISP members alone are two thirds of the exchange.

The venue's own data page is explicit about where these numbers come from, stating that its internet-exchange data is sourced from internet exchange operators, network operators, data center operators, PeeringDB and manual research, and recommending PeeringDB for deeper peering data (data sourcing). That is a transparency statement about provenance, and it is also a warning about precision: this is a curated snapshot of self-reported registry entries, not an audited count.

What the snapshot does not say

The honest reading of the September 2026 snapshot is that it measures who is listed, not how much traffic moves. Three limitations are material.

First, the breakdowns do not close. The country-of-registration list accounts for 46 of the 47 reported members, and the network-type list also accounts for 46. One member is unaccounted for in each list. That is a small discrepancy, but it means any percentage computed from these lists carries an unquantified remainder.

Second, the figures are a snapshot with a stated last-sync label, not a continuously verified count. Membership moves; the page does not move with it in real time.

Third, and most consequentially, the retrieved evidence contains no port counts, no traffic volumes, no counting of peering agreements and no pricing terms. Without them, the exchange's scale can be described in members but not in capacity. A 47-member exchange with a handful of large access networks can carry far more traffic than a 47-member exchange of small networks, and nothing in the available record distinguishes the two cases. Any claim that the 2013 order reduced consumer prices or measurably improved domestic latency would go beyond what this evidence supports.

There is one more boundary worth stating. Some of the designation and order detail rests in part on a third-party publishing-platform article rather than an official DOST-ASTI or DICT release, so that portion of the account carries lower institutional weight than a government publication would. Where a claim matters, this article has preferred the institute's own release and the operating data page.

Why a state-run exchange mattered here

The mechanism is policy-first exchange building. A national administrative order converts scattered government demand into something a network can connect to once and serve repeatedly. That demand raises the value of joining for commercial internet service providers and, in principle, for content and cloud networks seeking to reach Philippine users domestically. A non-profit, carrier-neutral operator keeps the cost of ports and peering off a commercial margin structure, so joining does not mean paying a competitor.

The result visible in September 2026 is a membership base that is overwhelmingly domestic and disproportionately made of access networks. That is the profile of an exchange that is doing the unglamorous domestic work well — carrying Philippine traffic between Philippine networks — and simultaneously not yet the profile of an exchange where large content and cloud platforms aggregate. Members registered in the United States, Hong Kong and Japan total seven. Whether those are remote content networks, international carriers or Philippine-linked entities registered abroad is not established by the available data.

The routing-security figure is the most striking number in the set. RPKI adoption of 41 of 47 is high for an exchange of this size in this region, and it is the kind of operational property a neutral state operator can plausibly influence by requiring or encouraging signed routes from members. It is an adoption statistic, not a measure of route validity or attack resistance.

The directory record for the exchange, maintained alongside this article, is available at PhOpenIX in the BTW directory.

What to watch

Three observable items would materially change this picture. A published port-capacity or traffic figure would convert a membership count into a scale claim. A dated, first-party DICT or DOST-ASTI record of the equipment turn-over and the designation would remove the present reliance on a lower-weight transcription. And a membership list showing a material shift toward content and cloud network types would indicate that the policy-first model has moved beyond domestic access-network interconnection.
