Dec 1, 2025

December 2025: Teleport engineering delivered key reliability and performance enhancements across authentication connectivity, reverse tunnels, and application watching. The team exposed configurable reconnect backoff for auth; added an agent-side watchdog for SSH connections with keep-alive health checks; and redesigned the app server watcher for faster resolution, reduced cloning, and standardized staleness policies. These changes improve resilience in intermittent networks, reduce operational churn, and scale efficiently for large app fleets. No major bug fixes were reported this month; instead, we focused on stability, consistency, and maintainable configuration.
