Multi-agent diagnosis of every fault against your own docs — cited — then a field tech in the loop before dispatch.

Today
A national carrier runs tens of thousands of cell sites. Any one can fail at 3am — a rectifier, a transport link, a power plant.
The clock
From minute zero an SLA clock is running. The alarm storm lights up dozens of nodes and hides the one site that matters.
The shift
The senior engineers who could read a fault by instinct are retiring. That instinct doesn't scale — and it doesn't answer the phone at 3am.
The question
What if every fault got the instinct of your best engineer — grounded in your own docs, and never dispatching a crew without a human's say-so?
That is Arc: specialist agents under one Orchestrator, reasoning on Vultr and answering to a human in the field.
The site
Racks, transport links, the −48 V DC power plant, the patch panel — down to the operator's phone. Every node feeds the live signal stream, and when a single rectifier drifts the whole site is on the clock.

Correlationfuses the alarm storm with the network topology to isolate the one site that matters — and its equipment class.

The live event log, the network topology, and the agent's reasoning — from the first anomaly at PAR-021-NORD to the confirmed dispatch, on one screen.
See it in action
One incident, a few minutes: detection, grounded diagnosis, the field veto, then remediation and a cited action report.
The field-validation loop
The moment Root-Cause lands a hypothesis, a push hits the on-call technician's phone. They test it on-site: confirm, and the pipeline advances; refuse — with a counter-measurement — and the agent pivots and re-diagnoses. The human always holds the veto.
