Something impacting routing/stability in SoCal?

Since Monday I've been plagued by massive lag spikes in all aspects of my internet use. It's most noticeable when gaming, as it's making GW2 completely unplayable. I'm literally disconnecting every few minutes, and nothing seems to make a difference. Streaming and even ordinary web browsing are also affected. Have rebooted computer, modem, router, etc. But the tracert (especially in concert with the Google attack map) seems to indicate a network node problem somewhere. Can someone official confirm or deny node related issues so I can stop making myself crazy trying to troubleshoot our (heinously expensive) connection and equipment?

Typical tracert to GW2 servers. (Yes, I'm annoyed I can't play my game. I'm not throwing a fit or anything, but it's a holiday and I was looking forward to it.) The lost packets are always at hops 7-8, absolutely without fail. As you can see the rest of the route looks fine, and the pings are always < 50, often < 40.
