What the network holds right now

Every active event in one subscribed disc, fed by the same stream a customer subscribes to — nothing staged, nothing replayed. Read-only by design: publishing has its own instrument on the home page. This page’s job is depth, which is what makes it the debugging tool for the question every integration eventually asks — why did I not receive that event?

A network is an assembly of small discs

The same subscription from six hundred kilometres up, drawn at its true size — not coverage we claim.

The network

3 subscribed areas · 8 km each
Three subscribed areas, drawn to true scale — which at this altitude makes each one thinner than the ring pointing at it, and that is the finding rather than a rendering problem: eight kilometres against six hundred is why a national network is an assembly of small discs and not one large query. 15 live around Paris; the other two are dark because this page holds one subscription at a time — select another watch point to light it. · © MapTiler · © OpenStreetMap contributors

The filters narrow what this browser’s subscription already holds — nothing is re-queried. The page deliberately subscribes to the whole disc with no type filter, because a debugging tool that pre-filters the wire cannot answer why something did not arrive. Events disappearing on their own schedule is the product working: natural expiry sends nothing, and the deadline was in the envelope all along.
