I have Comcast and no issues, my buddy has a local ILEC fiber connection. For over a month cannot play more then one activity, could be flying to the tower or one strike or gambit. Then Newt. Bungie can you check the server/s and network switches that handle traffic from various fiber based internet providers? I would be willing to run traceroutes or protocol scans with your IT guys from my buddies place to help find the disconnect. But this issue is truly hurting my friend and a glimpse of the forums says he not alone. We all love your game, help us find the issue so it calm be fixed please.
