The ArcGIS Online routing services (which are used by ArcGIS Pro when the network data source is www.arcgis.com) were updated on August 31, 2023 to use a new routing algorithm. So the change in routes you see now is most likely due to that algorithm change.
In order for my team to look into this further, can you provide us with additional information specific to your analysis such as the input incidents, facilities, barriers and the analysis settings you are using? There are a few ways you can send me the required information
- You can resolve the analysis in ArcGIS Pro and send me the job ID that ArcGIS Pro returns for this analysis along with date and time the job was submitted. To get the job ID, solve your Closest Facility layer and then open Solve history. This should open a dialog with details about the solve where you will find the date and time as well as the job ID that was obtained to execute the solve.
- If you do not wish to resolve the analysis (because it will need service credits), you can also create a layer package from the closest facility layer and then send me the .lpkx file at dmandloi@esri.com
Thanks
