Arbiter system status

Arbiter publishes live service availability and authentication latency. Our public status page is updated every minute and includes 90 days of visible history, including p50, p95 and p99 authentication latency metrics across regions.

Measurements are taken continuously by cloud-based probe workers hosted across three European locations: London, Amsterdam and Paris. Each probe fires every 15 seconds per region, testing both MAB and 802.1X authentication against the live service.

We report service health as the headline number: the percentage of probes that received the correct authentication result. A drift (service replied with the wrong answer) and an error (no reply or timeout) both count against health: for a NAC service, an answered request with the wrong policy decision is still a service failure. Reachability (drift-tolerant) and the drift and error counts are surfaced as supporting metrics on each card so the underlying breakdown is visible.
