# PORTNET (portnet.com) — Singapore's maritime/trade single-window, blanket-blocked

**What it is:** PORTNET is the Networked Trade Platform / Digital Port system operated for
Singapore's Maritime and Port Authority (MPA) and PSA — vessel calls, cargo manifests, customs
declarations. It requires a registered trading-company account; there is no public anonymous
tier.

## Observed

1. `GET https://www.portnet.com/` → **`HTTP/2 403`**, `server: AkamaiGHost`,
   `content-length: 1849`, `cache-control: no-cache, no-store, must-revalidate`,
   `server-timing: cdn-cache; desc=HIT` — Akamai's edge serves the block page directly from
   cache; this is a bot/access-control rule at the CDN edge, not an origin-level auth check
   (no `WWW-Authenticate`, no app-level login redirect).
2. `GET https://www.portnet.com/api/` → **identical** `403`, same `content-length: 1849`,
   same Akamai headers — the block applies uniformly to the marketing root and the API path
   guess; there is no distinguishable "real but gated" vs "doesn't exist" signal here, unlike
   Zenodo's generic-404 case or Domain.com.au's distinguishable-403-vs-404 pattern recorded
   previously. Every path tried returns the same byte-identical Akamai denial page.
3. `mpa.gov.sg` itself (the regulator, separate from PORTNET) is **not** blocked — its root
   loads normally (`301` to `/home`, CloudFront-fronted, Sitefinity CMS) — so the refusal is
   specific to the commercial trade-platform property, not the `.gov.sg` domain generally.

## Why it matters

Matches this lane's hypothesis directly: Singapore's "Digital Port" platform is reachable at
the TCP/TLS layer but refuses every request uniformly at the Akamai edge — a clean
refusal-not-geoblock shape (same egress IP reaches `mpa.gov.sg` fine), and one with no
information leakage about which paths are real.

How observed: 2026-10-05T10:42:52Z–10:42:53Z, two `GET`s via curl, `--max-filesize 20000000
-m 20`; `mpa.gov.sg` root checked for contrast at 10:42:39Z.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
