Resolved after 23 hours 2 minutes, affecting Sandbox execution (Sandboxes), on April 28, 2026.
Due to a code change, CIDR allowlists were applied too aggressively, and egress used for some sandbox functionality (including tunnels, exec API, filesystem API, and connection tokens) was unintentionally blocked. A fix has been merged and is being rolled out.
