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.

I cannot comment on Sharepoint, Word, Excel etc etc etc but I did notice it when using Outlook 365. Noticing this certificate issue for myself on my computer, I did some research and discovered that if you turn off the "Coming Soon" button in the top right corner of Outlook, the "Invalid Certificate" issue went away.
It seems to me that by activating this part of office, it is allowing Microsoft to send adverts about their products. I am lucky that I am using Windows 7 where that OS was never designed to be one large advertising platform where Windows 10 is.
I haven't investigated too deeply but after seeing this thread, I though I would give my 2 cents worth. I hope it helps some people out.
Cheers.

How can I disable and/or opt-out of this service?
Our SharePoint implementation is extremely slow. Hundreds of files are downloaded on every request, many of them unnecessary, and this represents a large portion of them. I'm trying to speed up the user experience. Please do not respond by saying it is a necessary feature, or that it doesn't affect our site, because both of those responses would be wrong and unhelpful.
Thank you.
If you are getting that kind of problem, it sounds like your caching policies aren't quite right.
I just did a quick test loading a SharePoint document library and I got just 83k transferred. A 100 or so requests.
The issue raised here wasn't a performance one but an identification and security issue which Microsoft have finally answered.
However, I can say that I blocked this domain for quite a long time and didn't see any issues.
Thanks! I will try blocking this domain.
Regarding caching, everything seems to be cached except for client-side web part queries (as expected), footprint activity (calls from fp.js), and a vast array of owa/o365 calls. It's the latter two that I'm trying to eliminate from my site. I don't need alerts from O365, and I don't want to participate in "customer improvement" programs.

Therein lies the irony - to identify performance issues - when I am getting a timeout from said server / cert! And eventually blank screen (Chrome) Browser crash (IE 11), I don't even want to try in Edge!
Replicate on SharePoint online by switching a fairly substantial list between Modern and Classic view.
If it is performance this is trying to fix - then I recommend someone in MS switch it off first!
- seems you are still using these kind of URLs ?

Responding to your old reply. has this url been updated on Microsoft allowed url list? I am still unable to find this listed in any of following article. https://learn.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide&redirectSourcePath=%252fen-us%252farticle%252fOffice-365-URLs-and-IP-address-ranges-8548a211-3fe7-47cb-abb1-355ea5aa88a2
https://learn.microsoft.com/en-us/microsoft-365/enterprise/microsoft-365-endpoints?view=o365-worldwideIt's been 5 years and there is nothing about this domain on official microsoft documentation websites. Better yet, I've started seeing this coming not from office, but from Windows Search. Here's a screenshot from ESET Protect report from one of our computers.
Peter86PLIn my case I get CAPI2 certificate errors and event viewer, which is how I found this domain, and one of the errors I regularly get lists the url *.footprintdns.com and the process associated with it it lsass.exe... I do not have even have office or outlook installed on this pc. Microsoft please give us an update!
