Can't trace to their servers. They are set to not respond to ICMP. At best, you will get to the edge router for their provider. This is fairly common practice... lock addresses down by default, and only allow the required protocols/ports. There are some addresses within their subnet that do respond though, but they do not publish them so will not post them here. Someone savvy with DNS/BGP digging can find them with some basic testing tools though. As an alternative, can test against the Seattle Century Link site at speedtest.net . Bellevue is very close by... to the east on the other side of Lake Washington. Level3/Century Link is also one of their primary peers, which also makes it a good test target in general (they carry roughly 40% of their traffic). If you poll netstat or something similar while that test is running you can capture the actual IP address for that site if you want to run traces and such. What you really should be capturing though are the UDP transfers between cloud servers and player addresses in play while you are having issues. That is where the gameplay data is going back and forth... not Bungie's local servers. That traffic is mostly tracking data, account authentications, inventory management, etc.
