What is the domain "nrb.footprintdns.com"??
The domain nrb.footprintdns.com is owned by Microsoft and represents servers in Microsoft datacenters. It is used for telemetry purposes that comply with Microsoft privacy commitments that you can read about at: https://products.office.com/en-us/business/office-365-trust-center-privacy. Data sent to this domain is used to identify network connectivity and performance issues and to support improvements to the service. We have plans to rename it to be more descriptive, and to publish it at the Office 365 IP Address and URL publishing site at http://aka.ms/o365ip. If you have any problems using Office 365 related to this, please raise a support incident so that we can assist at https://support.office.com/
Why is there no response from Microsoft on this?
This domain is blocked by my adblocker under the category "Spyware filter" though it is clearly owned by Microsoft.
We need an official explanation of what this is doing. Most importantly, we need to understand why this is not listed in the official URL list for Office 365.
We also need to know the impact of this domain being blocked which is clearly is being by some security tools.
Fiddler to my sharepoint site displays this: The server (0d255cb7441615dbb825de4d81cddac7.nrb.footprintdns.com) presented a certificate that did not validate, because it was issued to a different host.
Well since Microsoft have declined to respond. I recommend that everyone just blocks access to the domain.
