Known Limit
After review by the development team, it has been determined that this issue is related to a known limitation with the software that lies outside of Esri's control. The issue's Additional Information section may contain further explanation.
Additional Information
This is a a known limit. The service area algorithm with detailed option is using our old TIN based approach and it can have these spikes when it cannot find constraining edges to put into the TIN to generate a better service area. If you change the service area to be a larger value like 2.0 the problem will go away for these cases as more edges are traversed.
Is it acceptable to build a service area index and then use the generalized option?
