Intercom is the AI-first customer service platform used by thousands of SaaS companies for live chat, automated support, and customer engagement. When Intercom goes down, your customer messaging disappears from your product, support conversations stop, and Fin AI falls silent. Understanding whether it's a full outage or a partial degradation is the first step in responding effectively.
Intercom Failure Modes: What's Actually Down?
Intercom has several distinct layers, and they can fail independently. Knowing which layer is affected helps you respond correctly:
| Component | What Breaks | How to Verify |
|---|---|---|
| Messenger Widget | Chat bubble doesn't load on your site | Check browser console for CDN errors |
| Intercom Inbox | Agents can't access conversations | Try app.intercom.com directly |
| Fin AI | Automated responses fail or slow | Check AI component on status.intercom.io |
| Notifications | Email/push notifications delayed | Test a manual notification send |
| Webhooks | Integrations stop receiving events | Check webhook logs in Intercom settings |
How to Check if Intercom is Down
1. Check the Official Status Page
The Intercom status page at status.intercom.io breaks down health for: Messenger, Inbox, Notifications, Fin AI, Webhooks, and the REST API. Subscribe to status updates to receive email alerts when incidents are posted.
2. Check the Browser Console
If your Intercom Messenger widget isn't loading, open browser developer tools and check the Console and Network tabs. Errors loading widget.intercom.io or js.intercomcdn.com indicate a CDN issue rather than a backend problem.

- Fin AI Overload: Heavy AI processing demand can cause the Fin AI component to become degraded while the rest of Intercom stays functional.
- Webhook Queue Backlog: When Intercom's webhook delivery system gets backed up, integrations with CRMs, Slack, and Zapier experience delayed or missing events.
- CDN Failures: The Messenger widget loads from Intercom's CDN. Regional CDN outages can prevent the widget from loading for specific geographies.
- Database Scaling Events: High-growth traffic spikes can cause temporary Inbox slowness during database autoscaling operations.
- Third-Party AI Provider Issues: Fin AI relies on LLM providers. When those providers have issues, Fin AI responses slow down or fail.

Frequently Asked Questions
Why isn't the Intercom chat bubble showing on my site?
This is usually a CDN loading failure (check browser console for errors), a conflict with your Content Security Policy (CSP), or a Messenger-specific outage listed on status.intercom.io.
Are my Intercom conversations lost during an outage?
No. Intercom persists conversation data in its database. Messages sent during an outage may be delayed but should eventually deliver once the service recovers.
How can I get notified of Intercom outages?
Subscribe to updates on status.intercom.io, or use API Status Check to set up automated monitoring with SMS/Slack/webhook alerts for faster notification than Intercom's own status page.
