On or shortly after February 9, 2026, the Astro Control Plane's outbound IP addresses will expand to also include 104.43.242.104/30. If you have allowlisted the Control Plane IP addresses for purposes of controlling access by the Astro IDE, Astro Observe Snowflake integration, or webhooks from Astro Alerts, please add this new CIDR range to your allowlist or your firewall may block some traffic from these services. For Astro users who have not applied a firewall to these services, no change is needed.
Normal operation of Airflow tasks and DAGs will not be affected. External IPs for Deployments are also not affected by this change.
