Zendesk powers customer support operations for over 100,000 businesses โ from startups to Fortune 500 companies. When Zendesk goes down, support tickets stop arriving, agents lose access to customer history, and customer satisfaction scores drop in real time. Knowing how to quickly diagnose and respond to Zendesk outages is essential for any support operations team.
How to Check if Zendesk is Down
1. Visit the Official Zendesk Status Page
Zendesk's status page at status.zendesk.com shows real-time health for Support, Chat, Talk, Explore, Guide, and the Zendesk API. Zendesk operates multiple data center regions (US, EU, AU) โ check if the issue is global or region-specific to your data center.
2. Check Your Zendesk Subdomain Directly
Try accessing your Zendesk subdomain (yourcompany.zendesk.com) directly. If your account page loads but tickets aren't appearing, the issue may be with email ingestion rather than the web interface.
3. Test the Zendesk API
If you use Zendesk's API, test the endpoint to isolate whether it's the web interface or API layer that's affected:
curl -s -o /dev/null -w "%{http_code}" \
https://yourcompany.zendesk.com/api/v2/tickets.json \
-u "user@example.com:your_api_token"

4. Check DownDetector and Social Media
A spike in DownDetector reports combined with Twitter/X activity usually confirms a widespread issue. Support administrators frequently share workarounds on social media during Zendesk incidents.

Understanding common failure modes helps you respond faster:
- Email Ingestion Failures: The most common partial outage โ the Zendesk web interface works but new tickets from email stop arriving. This is usually a mail server or routing issue on Zendesk's end.
- Database Replication Lag: Large enterprise accounts with high ticket volumes can experience replication delays that slow ticket loading and search.
- API Rate Limit Enforcement: High-volume API consumers can trigger rate limits that look like downtime to other API users on the same infrastructure.
- Authentication Service Issues: SSO (SAML/OIDC) integration failures can prevent agents from logging in even when the core platform is healthy.
- CDN and Network Routing: Zendesk relies on CDN providers for global delivery. Regional CDN failures can cause access issues for specific geographies.

Frequently Asked Questions
Is Zendesk down for everyone or just my company?
Check status.zendesk.com. If the status is green but your instance has issues, it may be specific to your Zendesk subdomain region (US, EU, AU) or your email forwarding configuration.
Why are new Zendesk tickets not appearing?
If your Zendesk dashboard loads but tickets are missing, the most likely cause is an email ingestion issue. Check your email forwarding setup and verify status.zendesk.com shows no email routing issues.
How do I check Zendesk's historical uptime?
The Zendesk Status page (status.zendesk.com) maintains an incident history. You can also check third-party monitoring services for historical uptime data.
