How to read this
- ·Handshake latency is one measurement from one probe, from our infrastructure. It is a smoke signal about the endpoint, not a benchmark of your own connection to it.
- ·An authentication challenge counts as responding. A hosted server that refuses an anonymous prober is behaving correctly.
- ·A tool count of “behind credentials” means the handshake worked but listing tools needed a token we do not hold.
- ·Uptime covers the last 30 days of our own checks, at most one an hour, and says how many checks it is drawn from.
