This is not what happens in practice because query anomalies tend to
come in clusters, either because customers in the same region tend to
pick up similar malware or because they deliberately use the same
nominally non-malicious software which exhibits query anomalies
(perhaps because you've shipped it to them yourself).

Reflection through broadband routers is a possibility as well,
unfortunately.
