However, Round-Trip Time (RTT) measurements of 18.0ms contradicted the claimed geographic distance of 5976km, indicating a geolocation inconsistency. The surrounding neighborhood was classified as mostly clean with an abuse density of 0.0805. Network scans returned no open ports, and the service purpose was noted as Firewalled.

The overall confidence level was assessed as Very Low (0.125) due to signal contradictions and insufficient data sufficiency.
