Your domain is your status page.

When downtime hits, visitors stay on your URL and see a branded offline page instead of an error. When you recover, they're redirected automatically. No third-party status page to maintain. No manual updates. No forgotten "we're back!" posts.

Outage confirmed

Consensus reached — your origin is genuinely down

Worker route activated instantly

Cloudflare intercepts requests and serves your offline page

Recovery detected — route removed

Traffic flows back to your origin automatically

Works on Cloudflare's Free plan

Cloudflare Workers includes 100,000 free requests per day — more than enough to serve your offline page during any outage. No paid Cloudflare plan required.

Use the default page or provide your own custom HTML. Just needs a Cloudflare API token with Worker Scripts and Workers Routes permissions.

Not All Outages Are Created Equal

Detection speed depends on how your site fails. A hard crash is caught in seconds. A slow timeout takes longer to confirm — but we still catch it.

Why the range? Every check requires consensus — multiple nodes must independently confirm the outage before an alert fires. This eliminates false positives but means detection time scales with how long your server takes to fail.

You can configure per-domain timeouts to fine-tune detection speed for critical services.

Everything You Need

Multi-Node Consensus

No more false alerts from a single node's network hiccup. 2+ servers must agree before an incident is confirmed.

Response Time Tracking

Track response times from each location. Get degraded alerts when your site is up but slow, with configurable thresholds.

Content Matching

Verify your page returns the expected content, not just a 200 status. Catch silent failures like error pages or blank responses.

Cloudflare Offline Pages

Automatically deploy a branded maintenance page via Cloudflare Workers when your origin goes down. Deactivates on recovery.

Maintenance Windows

Schedule maintenance windows to suppress alerts during planned downtime. Set specific days and time ranges.

Repeat Alerts

Optionally re-send alerts every 30 minutes during extended outages so incidents don't slip through the cracks.
