The We Need Broadband Campaign is gathering info from folks who need broadband and compiling it for a map. So far I see one flag for Minnesota.
I don’t think this is particularly scientific or official but kind of fun. So if you need broadband think about filling it out. It does look like they will make this information available to providers so you might hear from someone who can help you. (Of course if they’re sharing info, you may hear form folks you don’t want to hear from too.)
