The two resolvers we were given are not located in the US, so we are being returned IP addresses of Microsoft cloud infrastructure located in Europe.
microsoft.graph.com is a good example but there are many others, it's serving up edge locations that have longer travel time.

Are there any plans to have more geographically appropriate resolvers that will provide geographically appropriate edge destinations?
If you could please update SWG-I-101, to include the performance aspect.
