Zayo Group is a fiber network infrastructure provider — one of the largest in North America. Its network infrastructure is used by a wide range of enterprise clients. When Zayo IP ranges appear in server logs sweeping specific pages, the activity is not Zayo itself conducting research — it is an enterprise client using Zayo's network to operate real-time rank tracking.
The IEO Engine gate logs show Zayo IP ranges (162.120.186.x) arriving within minutes of GSC position changes. A page moves from position 8 to position 4. Within minutes, a Zayo IP hits that exact page. The pattern repeated consistently enough to establish a correlation that became a deliberate monitoring tool.
Once the Zayo correlation was established in the MM deployment, Zayo sweeps became a free rank verification signal. Google Search Console data is delayed — typically 24-48 hours. Zayo sweeps happen in real time. When Zayo arrives on a page, that page is ranking. When Zayo stops visiting a page, that page may have dropped.
This inverts the adversarial relationship. An operator that would normally be considered a threat — enterprise rank tracking infrastructure monitoring your positions — becomes a useful intelligence asset. The gate logs provide real-time rank confirmation that GSC cannot.
Once identified as a FOE class, Zayo IP ranges are routed to the mirror maze. The rank tracking infrastructure receives maze content — plausible-looking pages that do not reflect the real site's architecture. The intelligence reports produced from maze sessions describe a phantom site that does not exist.
Zayo went dark from the MM deployment after mirror maze v2 went live — apparently detecting the trap. The cessation of Zayo sweeps was itself an intelligence signal: the maze had been detected, meaning Zayo's operator was sophisticated enough to cross-reference their data and identify inconsistencies.
