Uptime methodology

Synthetic monitors (status page)

/status/ surfaces externally monitored probes (e.g. UptimeRobot) against published HTTP endpoints. “Up” here means probes received sane HTTP responses inside configured intervals — not infinite application-layer coverage.

Synthetic vs human-perceived outages

• Geographic vantage matters — probes may differ from your office ISP path.
• Authoritative downtime for credits under SLA follows SLA measurement rules (full SLA) — correlate tickets with timestamps.

Real-user assurance (recommended)

Run your own uptime checks against critical flows (checkout AJAX, webhook callbacks, SMTP submission). Synthetic green does not forgive misconfigured CDN cache rules or database deadlocks confined to POST routes.
