UN Relay Directorate — the UN body that operates the relay layer of the settled system’s communications network, created in 2101 when the cislunar network section of the dissolved UN Office for Lunar Affairs was reconstituted under direct UN authority by Article IV of the Charter of 2101. It runs a chain of laser trunk stations, with ground and orbital terminals at each settled body and two relay stations on Earth’s orbit sixty degrees ahead of and behind Earth to see around the Sun during conjunction. The network is store-and-forward: every message, page, payment, and file travels as a sealed bundle held at each node until its next transmission window, and the Directorate sets six priority classes — distress and safety, governance (including CAI/Oracle queries and recommendations), navigation and fleet traffic, clearing and administration, UN publication, and everything else — that decide what moves first in a congested window. Bundle contents are sealed to the Directorate, which reads addresses and keeps routing records; off Earth the relay is funded by the UN and free at the point of use, as former UNOLA relay engineer Mirela Constantin described in How the UN Relay Works Across the Solar System (2102).

The 2195 Citizen’s Guide records governance traffic as class 2 and private traffic as class 6, and notes that Mars’s Soviet-built body network passed to the Martian Provisional Authority while the relay itself remains UN-owned. The independent belt stations remain outside the Oracle’s reach by geography — one of the Sovereign Miners’ Coalition’s grievances since before the Compact.

The Authority’s October 2184 communications audit found the same arrangement from the Martian side: a Soviet-built body network maintained under a manufacturer’s contract, a UN-owned relay node, and governance traffic queued in class 2 against private traffic in class 6. “We did not build it, we do not maintain it, and we do not decide what it carries first,” the communications office’s summary read. The Consulate’s own bulletins travel in class 2.

Range chart of one-way signal times between inhabited points in 2102, on a log scale: Earth–Luna about 1.3 seconds; Luna–Mars about 3–22 minutes; Luna–Ceres about 13–33 minutes, with the best possible answer taking 26 minutes round trip; Mars–Ceres about 8–38 minutes; Luna–Jupiter about 33–54 minutes. A shaded live zone covers sub-second delays — the local and body layers — bounded at one second round trip; every inter-body link except Earth–Luna takes at least three minutes each way. A note records that for two weeks every 26 months the Sun blocks the Luna–Mars line, and that two relay stations 60° ahead of and behind Earth see around it. The reading notes that a letter from Ceres to Luna is delivered in half an hour, and that asking the post for an obscure page on Luna can take an hour. The footer lists the three layers — local, body, relay — and the six queue classes, with class 6 waiting for whatever capacity is left.
