# A probe is watching
within 90 seconds

Synthetic HTTP and gRPC assertions, executed every ten seconds from bare-metal POPs in 28 transit centers. No agents on your fleet, no sidecars to babysit — the first probe is running before you finish reading this page.

## How it is wired

Probes run from physical tier-1 transit facilities, not shared cloud VPCs, so what you measure is the network your users ride — not cloud peering bias. One trace, three stations.

### Bare-metal, not lambdas

Probes live in tier-1 transit facilities. The RTT you see is the RTT your users get.

### Assertions, not pings

JSONPath body checks, gRPC status codes, TLS certificate expiry — a check fails when your product fails, not when a packet does.

### Your telemetry, your tools

Export to the Prometheus and OpenTelemetry you already run. No dashboard to live in, no lock-in to migrate off.

## One frame, all 28 POPs

A single assertion — `GET /health` against a Seoul origin — fanned out to every POP at the same instant.

Per-POP readings for one assertion: DNS, TLS, TTFB and p99 over 24 hours

…22 more POPs in the console — same frame, same instant

Measured 2026-08-20 14:00 UTC · 10 s interval · n = 8,640 per POP · milliseconds, median of the hour shown for DNS/TLS/TTFB.

## Priced per probe,
not per seat

A probe costs the same whether three engineers or thirty look at the console. Downgrade, pause, or delete from the CLI.
