| # Isolate n8n | |
| By default, a self-hosted n8n instance sends data to n8n's servers. It notifies users about available updates, workflow templates, and diagnostics. | |
| To prevent your n8n instance from connecting to n8n's servers, set these environment variables to false: | |
| ``` | |
| N8N_DIAGNOSTICS_ENABLED=false | |
| N8N_VERSION_NOTIFICATIONS_ENABLED=false | |
| N8N_TEMPLATES_ENABLED=false | |
| ``` | |
| Unset n8n's diagnostics configuration: | |
| ``` | |
| EXTERNAL_FRONTEND_HOOKS_URLS= | |
| N8N_DIAGNOSTICS_CONFIG_FRONTEND= | |
| N8N_DIAGNOSTICS_CONFIG_BACKEND= | |
| ``` | |
| Refer to [Environment variables reference](/hosting/configuration/environment-variables/deployment.md) for more information on these variables. | |
