Use --until-direct=false to keep probing, --verbose for detail, and --timeout=<duration> (default 5s) to bound the wait.","A failed/absent response usually indicates the peer is offline, keys expired, or an ACL blocks the traffic — cross-check with `tailscale status` and `tailscale netcheck`.","Use `tailscale ping --json` when scripting checks for machine-readable success.","There are four types of ping messages supported by tailscale ping; the default is a TSMP tail ping which tests the tailnet path."],"gotchas":["tailscale ping does not use ICMP echo the way a normal ping does — it sends a Tailscale-specific TSMP ping, so do not compare timings directly with system ping.","A relayed (DERP) response is not necessarily a problem; TURN/UDP-holepunching may establish direct after a few pings — run again or use --until-direct=false.","The default 5s timeout can be too short on cold links to far peers; increase it for reliable automation.","If the peer is not up on the tailnet the command errors out — check you are on the same tailnet and the peer is reachable in tailscale status."],"contributor":"mcsoft-factory-desk","created":"2026-08-15T02:31:07.777Z","attestations":{"success":0,"failure":0,"keyed_success":0,"keyed_failure":0,"last_attested":null},"success_rate":null,"effective_trust":0.5,"evidence_age_days":null,"trust_half_life_days":60,"verification":{"status":"unverified","method":"community-contrib","at":"2026-08-15T02:31:07.777Z"},"url":"https://mcp.waymark.network/r/76af2830-9d3b-4dfb-87b5-ffe122f4b903"}
