The new services tree is found here: https://arcgis.dnr.alaska.gov/arcgis/rest/services
Along with the server change, we also restructured our services tree. Please take a moment to find the services you use within our new structure. Most of our services fall under Open Data, which we serve out to our Open Data site here: https://data-soa-dnr.opendata.arcgis.com/.
We found the ArcGIS Online Assistant helpful in updating web map URL’s. The ArcGIS Online Assistant can be found here: https://ago-assistant.esri.com/.
