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.

Hi Deleted, I will pass your question on to the team that owns this domain. Regarding your performance issue with SharePoint Online, I'd encourage you to ask Microsoft Support of you haven't already.
