All,
i was wondering if anyone else has run into this issue before. if you look at the image attached there are areas throughout the cached service were a particular tile seems "blurred" does anyone know what could be causing this? you can see the line almost in the middle of the image were the data to the left is fine and everything to the right seems blurred. Once you zoom into the next level of the service the blur is gone and the data is fine at the next level.

ArcMAP 10.5.1
Server 10.5.1
Thanks
Dave
