What does the "t-msedge.net" content on the osm.org website do?

I could find no sources on this online.

UBlock-Origin shows me that openstreetmap.org loads content from the origin t-msedge.net. The logger shows this

screenshot of the UBlock Origin logger, showing a block of the request to the domain dev.virtualearth.net while being resirected to a domain under t-msedge.net

From this output I assume that virtualearth requests these resources. The site https://virtualearth.net redirects to bing.com, so I assume Micro$ has bought it? Or was it always part of it?

Anyways, that domain is very odd, why does it have “msedge” in the name, as in “Microsoft Edge”? Researching on this, it may just be something with Azure. Here is the whois website, showing that it is owned by Micro$, nothing more.

Anyone know more about this?

I dont know, but would it be useful to only connect to Microsoft if the virtualearth map resources are actually selected? It seems they are always loaded.

These are the aerial image tiles from the Bing aerials. This is loaded in the iD editor when “Bing” is selected as the image source. E.g. https://ecn.t3.tiles.virtualearth.net/tiles/a0230123112111133312.jpeg?g=14875&pr=odbl&n=z

But I can’t reproduce that on the osm.org home page.

I suspect msedge means Microsoft's edge CDN server, not Microsoft Edge (browser)

Like mcliquid, I also don’t see requests to Microsoft when viewing openstreetmap.org home page.

This is screenshot of uMatrix when in incognito mode:

and when logged in, it only loads in my avatar from Gravatar:

I assume you are referring to when in edit mode (i.e. using iD). In that case, the code that is loading this seems to be here: iD/modules/renderer/background_source.js at develop · openstreetmap/iD · GitHub

Can you recheck this claim?

What you are seeing is the request for the meta data for the Bing maps tile layer, not for tiles themselves. If you are playing by the rules that allow us access to Bing maps, you need to query the API before you display tiles.

iD is running this for every user regardless of if you are actually displaying Bing tiles, as Bings meta data API is notoriously slow and unreliable, so you want to get this out of the way asap.

You should have read the above in the relevant privacy policy, if it isn’t pointed out, you should ask the OSMF to add a section as we do here Privacy - Vespucci (last section). In any case this is not something new and at least near to a FAQ.

Thanks guys for the explanations!

I think this sums it up well

  • Microsoft “Edge” CDN servers (they are just bad at naming things, huh “Copilot”?)
  • Bing maps, metadata always fetched
  • likely only loaded when in edit mode
