Runbook: Intapp Application Unavailable

Purpose

Use this runbook when Intapp is unavailable or users report access failures.

Symptoms

• Users cannot reach the application URL
• Login page fails to load
• HTTP 502, 503 or 504 errors
• Application Gateway reports unhealthy backend
• Multiple user impact reported

Initial Checks

1. Confirm the affected URL and user impact.
2. Check Azure Service Health.
3. Review Application Gateway listener and backend pool health.
4. Confirm DNS resolves correctly.
5. Check recent changes or maintenance activity.
6. Review VM, SQL and application monitoring.
7. Confirm whether the issue is infrastructure or application-layer.

Validation

Confirm:

• Application URL loads successfully
• Backend pool is healthy
• No active Azure platform incident is affecting the service
• Monitoring has returned to normal

Escalation

Escalate to Application Support if Azure infrastructure is healthy but the application remains unavailable.
