The ICHI score over time: the last week, four weeks, six months, a year or all recorded history, with monthly averages and how they moved, and any recorded day on request. Stored daily snapshots only — a day that was not recorded stays a gap.

Loading the recorded history…
Pick a date, or click a day on the chart.
Every value on this page comes from the snapshot stored for that day, or from an average or difference of stored snapshots. Nothing is reconstructed from today’s live state, a day that was not recorded is never filled, and averages use the current scoring methodology only. A higher score means more internet-wide risk.
