Uptime Monitoring
Round-the-clock checks on your websites and APIs from regions around the world. When something goes down, you know within seconds — before your customers do.
Know before your customers do
Ionhour probes your endpoints on the schedule you set, every minute of every day. The moment a site or API stops responding, an alert is already on its way.
No false alarms
Checks run from multiple regions around the world. A single slow region won't trigger a false alarm — only confirmed outages fire alerts.
SSL expiry warnings
Expired certificates take sites down quietly. Ionhour watches every certificate and warns you well before it lapses.
Latency, tracked
Response times are recorded from every probe region with P50, P95, and max percentiles — so a slow-down is visible long before it becomes an outage.
Map your service dependencies
Model the external services your app relies on — Stripe, Redis, auth providers. When a dependency goes down, Ionhour automatically propagates a DEGRADED state to every service that depends on it, so you see the blast radius instantly.
Instant Alerts
Get notified within seconds via Slack, Discord, SMS, email, or webhooks the moment a check fails.
Availability
Everything an uptime check should do
From multi-region probing to response validation and performance tracking.
Every check runs from probe regions around the world. An outage must be confirmed across regions before an alert fires — so you can trust every page you get.
