first seen 2026-06-11 11:39 · last seen 2026-10-31 12:01 · JSON
Last 7 days (5 observations)
Distinct clients per day (last 30 days, peak 29/day)
Distinct clients are counted by IP-hash per complete UTC day — unlike observation counts this is insensitive to one chatty client, but NAT merges clients and address rotation splits them.

Co-observed signals
Signals from other families seen in the same observation. A fingerprint spread thinly across many lower-layer signatures is a classic inconsistency signal.
