Hello ServiceNow Developer Community,
Please help investigate my inaccessible Personal Developer Instance and restore access while preserving all existing work.
Instance: dev443121
URL: https://dev443121.service-now.com/
Release shown in the Developer Portal: Australia
Observation period: October 15, 2026, approximately 20:32-20:50 JST (11:32-11:50 UTC). The exact start of the outage is unknown.
Observed symptoms:
- The Developer Portal is accessible and shows the instance assigned to my account.
- The instance remains Offline, including after Refresh completes normally.
- Opening the instance root URL directly returns "502 Bad Gateway" with "snow_adc".
- Start building is disabled.
- No Wake Instance or Restart option is available. The only enabled Actions are Release instance and View history.
- The management page shows 0 alerts, with no visible waking-up progress, maintenance details, or estimated recovery time.
The instance history shows successful Event Management and ServiceNow IntegrationHub Installer activations dated October 14, following an earlier failed Event Management activation. This is background only; I have no evidence that the plugin activity caused this outage.
Could the appropriate team check the backend health and startup status, clarify whether maintenance is in progress, and advise on a non-destructive recovery and estimated recovery time? Please route this report to the appropriate Developer Program team if backend intervention is needed.
Preserving the existing instance is essential. Please retain all data, installed plugins, configurations, and customizations. This report does NOT authorize a reset, wipe, release, reclamation, reprovisioning, or replacement. Please obtain my explicit approval before any action that could remove or replace existing content. I have not reset or released the instance.
Thank you.
