Interesting data, Debbie.
It looks like your cable ISP, Bend Cable, is having some problems with its connection with 360 networks (which owns the brands "Touch America" and "Group Telecom" - both represented in your traceroute).
At some point during collecrtion session, your ISP stopped routing data through Verio, and started routing through 360 networks - and that's when your problems started in the data you sent us.
I've attached a couple of pictures - one when your connection was OK, one when it wasn't. This is absolutely something you need to talk to Bend Cable about - they're in control here.
Here's the graph of the data you sent us, but the upper graph is zoomed in on just the good part of the graph.
