I am having a problem when solving some of my service areas. I am loading the locations from a point feature class, and they are all located. The majority of them return a service area that is appropriate (7 minute breaks, double checked with solving for routes), but a handful of them return something strange. The problem is that there are some areas of the specific service areas that are wildly inaccurate, and there is no way that it is a 7 minute distance, which I also checked. I have attached a picture of the problem, and I'm assuming that it has something to do with my network, but I have no idea what. Any help/ideas would be greatly appreciated.
The network is a walking network that was manually created, and I am using ArcGIS 10.
