FiveNines

Website & API Uptime Monitoring

Monitor your websites and APIs from multiple regions around the world. Know within seconds when a service goes down - not when your customers tell you. Multi-region probes eliminate false positives, and alerts reach you via Email, Slack, Discord, Telegram, Pushover, or Webhooks.

How It Works

Configure URL

Add the URL, choose check interval and alert preferences.

→

Probes Check

Multiple probes from different regions check your service independently.

→

Alert If Down

When probes confirm an outage, you're notified on your chosen channels.

→

Create Incident

An incident is created automatically with a full timeline.

Multi-Region Verification

Probes from multiple geographic regions confirm outages before alerting. No more 3 AM wake-ups because a single network hop had a hiccup.

Response Time Tracking

Track response times over hours, days, and weeks. Spot performance degradation before it becomes an outage. Historical data with full retention on your plan.

SSL Certificate Monitoring

Automatic SSL expiration tracking with configurable warning thresholds. Get alerted days or weeks before your certificate expires.

Alerts on Every Channel Your Team Uses

When an outage is confirmed, FiveNines sends notifications to the channels you have configured: Email, Slack, Discord, Telegram, Pushover, and Webhooks. Route different monitors to different channels - production endpoints to PagerDuty via webhook, staging to a Slack channel.

Each alert includes the URL that failed, which regions detected the outage, response time data, and the HTTP status code returned. When the service recovers, you get a resolution notification with the total downtime duration.

Response Time Graphs & Uptime History

Every check records the full response time, not just up/down status. View response time graphs over any time range to spot trends - a gradually increasing response time often predicts an upcoming outage.

Uptime percentages are calculated automatically. See your 7-day, 30-day, and 90-day uptime at a glance. Share these numbers with stakeholders or display them on your public status page.

Frequently Asked Questions

How does multi-region uptime monitoring work?

FiveNines checks your URLs from multiple geographic regions simultaneously. A service is only marked as down when multiple probes confirm the outage, eliminating false positives caused by localized network issues.

What check intervals are available?

Check intervals range from 30 seconds to 5 minutes depending on your plan. Starter plans include 1-minute checks, while Pro and Enterprise plans offer 30-second checks for faster detection.

Does FiveNines monitor SSL certificates?

Yes. FiveNines automatically tracks your SSL certificate expiration dates and alerts you before they expire, so you never get caught with an expired certificate causing browser warnings for your users.

How are false positives handled?

FiveNines uses multi-region confirmation before triggering an alert. If one region reports a failure but others succeed, it is treated as a localized network issue rather than a real outage. Only confirmed outages from multiple probes trigger notifications.

Can I display uptime data on a public status page?

Yes. FiveNines includes public status pages where you can share uptime data with your users. Monitors are automatically linked to your status page and update in real time.
