IP 40.99.227.210 was observed from 2026-09-09 to 2026-09-13 within the Microsoft Corporation network (ASN 8075). The endpoint operated as a CloudCompute web server, accepting traffic on TCP ports 80 and 443. TLS inspection identified a certificate issued to outlook.com by DigiCert Inc, with Subject Alternative Names covering Outlook, Hotmail, Live, and Office365 domains.
The IP held a Low Risk reputation score of 25. Threat intelligence feeds showed no association with known attackers, campaigns, or Tor exit nodes. Behavioral analysis reported zero incidents, honeypot hits, or enumeration strikes. Control plane data indicated one DNSBL listing within eight total lists checked. Geolocation data associated the address with Wyoming, United States; however, RTT physics validation flagged a contradiction, indicating the distance measurement contradicted the observed latency. Due to these signal contradictions and the general risk classification, the recommended action was to Monitor the address with low severity.
