Every number on this page is computed live from the same tables our alert engine writes. If our probes are unhealthy, you get to know before we do damage control.
Beta honesty note: three probe machines, one per continent — Amsterdam, Virginia and Singapore. That is fewer than anyone else advertises, and it means the default threshold is unanimity: all three have to agree before anyone is paged. A published false-positive rate follows once there's enough incident history to audit.
We don't cry wolf — and you shouldn't have to take our word for it. What upstream providers said →
