This endpoint has no current downloadable verification, or a newer check did not succeed. Previous measurements below are historical. Choose another checked Shadowsocks server.
Handshake is tunnel setup time; HTTPS first byte includes the request through that tunnel. Neither is an ICMP ping or a bandwidth measurement. The success rate covers stored full-tunnel attempts only; it is not continuous uptime.
Latest 3 stored checks, up to 100 per configuration. Checks belong to this configuration’s stable public ID; different configurations on the same host have separate histories. Preflight and policy results do not count as successful tunnels.

No recorded checks match this filter.
If it fails, compare the latest check time, try a different endpoint or report the problem. Public source configurations can change between checks.
The external checker completed a Shadowsocks tunnel, carried an HTTPS request and verified a changed public exit IP. This measures technical availability at that time, not the operator’s trustworthiness or performance from your network.
