Latency Over Time — Top 5 Regions
Fastest Nodes
What are DERP Servers?
DERP stands for Detoured Encrypted Routing Protocol — a cloud relay run by Tailscale for when a direct peer-to-peer connection isn't possible.
All traffic via DERP is still end-to-end encrypted. Tailscale can only see encrypted packets. This dashboard measures your latency to each global DERP server directly from your browser.
Notes
- Checks run every 10 seconds via HTTPS (TCP), so readings may be slightly higher than Tailscale CLI (UDP).
- If this tab is in the background, browser throttling may inflate latency readings.
- Some nodes may appear offline due to local network conditions or browser security policies, even if operational.
