What is the domain "nrb.footprintdns.com"??

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.

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 ?
