https://live.paloaltonetworks.com/t5/Customer-Advisories/Important-customer-information-regarding-PAN-DB/ta-p/235081 Dear Palo Alto Networks customer, On Thursday, October 11, 2018 at 7:01 AM PT, a Microsoft URL used by Office 365 (secure.aadcdn.microsoftonline-p.com) was inadvertently categorized from “Computer-and-internet-info” to “Phishing,” which may have impacted the availability of Office 365. As soon as we discovered the issue at 10:22 AM PT, we re-categorized the URL to “Computer-and-internet-info,” restoring access to impacted users. During the impacted timeframe, customers who have PAN-DB policies to block the “phishing” category would have been unable to access secure.aadcdn.microsoftonline-p.com, potentially preventing authentication to Microsoft Office 365. Root Cause We immediately began investigating the root cause of this important issue and determined it was due to a human error that resulted in the re-categorization from “Computer-and-internet-info” to “Phishing.” We apologize for any inconvenience this may have caused and thank you for your patience as we worked to resolve this issue. Should you have any questions, please don’t hesitate to reach out to your support provider or the Palo Alto Networks Support Team at https://support.paloaltonetworks.com. 10:22am PDT? That's around the time I submitted the URL re-classification 😉
