Know it's down before your customers do.
From 27 real regions.
HTTP, ping, port, keyword, DNS, SSL, domain expiry, heartbeat, and API contract checks. Verify uptime from where your users actually live — not from one datacenter pretending to be 'global'.
Every check type that matters
HTTP/HTTPS with status, latency, keyword, redirect-chain & TLS. DNS divergence. Port. UDP. Heartbeat for cron jobs. Domain & SSL expiry warnings.
27 real probe regions
Pick the regions that matter. Compare latency by region. Detect regional outages your single-location monitor would miss entirely.
30-second checks
As often as every 30 seconds on Business. Every 1 minute on Pro. We use sharded Cloudflare Workers — no shared queue, no noisy neighbors.
Honest verdicts
We classify failures (timeout / TLS / DNS / 5xx / keyword-missing). Bot-block status codes are not flagged as outages. No false-positive spam.
