# Measured Uptime — rpc.mnr.network

Uptime of the mnr relay (`rpc.mnr.network`), measured from Cloudflare every minute. Live numbers: [/status.json](https://mnr.network/status.json). Beta, no uptime promise: these are measurements, not a guarantee.

- **Up**: the relay answered `get_height` with a valid height.
- **Degraded**: it answered, but `/healthz` did not answer 200 (usually a degraded node pool).
- **Stale**: it answered, but the height had not moved for 60 minutes.
- **Down**: no valid answer twice in a row, 5 seconds apart.

Availability = (up + degraded + stale) / all measured minutes. Minutes where our own monitor token was refused are not counted. Minutes with no measurement are left out of the percentage, and each window reports its coverage (measured / expected minutes). The onion and I2P addresses are not measured. Node-by-node health: [/upstreams/](https://mnr.network/upstreams/).

## This pool, measured the same way

Every 5 minutes the same probe goes to the relay and, directly, to each public node in its pool: one `get_info`, 4-second timeout, one retry. Up = answered, synchronized, at most one block behind the median of the round. Refusals (401/403/429) are not counted as down; they lower coverage. One Cloudflare location per run; a low figure can reflect that path and is not a verdict on the operator. The nodes are run for free by volunteers and companies, and mnr depends on them. Figures: `comparison` in [/status.json](https://mnr.network/status.json).
