Hi Folks,
That looks like a "live" tile and does not have "Maps" in the URL. I suspect it is for the live MSN web tile service in Windows Phone but that is a wild guess just from the URL. With Windows Phone no longer on the market, I would expect that may be torn down, but again, wild guess. I can confidently confirm that it is not offered by the Maps team. Ronald, can you please provide the public API docs you used as guidance to leverage those tiles? I can't find anything about them so far.
It does look like MSN does offer https://learn.microsoft.com/en-us/connectors/msnweather/ so maybe it is related to that offering? However, I don't see a URL link like yours there either.
If you can provide me the instruction guidance you have for it's use, I can try and find who wrote that to find the service owner.
Sincerely,
IoTGirl
