    Please remove the site for Proctor Academy on your site under NH rest areas as this is a data breach and is not safe for our schools liability and is not good for the schools emergency management. We have NOT given permission for this access. Please respond.

      The list is not ours – we have merely reviewed the list here. But I will send your note to the creator of the list.

      @Lynn George – I curate the list of ArcGIS server addresses that Joseph Kerski reviewed. I just checked the list and there is nothing there for Proctor Academy. Since I update the list once a week it is possible that the ArcGIS server for your school was in an earlier version of the list.
