First let me point out that I'm not nearly as technically astute as most of you obviously are. This posting will probably be full of errors and missing info, so I apologize up front for any of that. If more/different info is needed, let me know.
I'm near Manchester NH. For the last two weeks I've noticed a huge slowdown in web response. I have a copy of VisualRoute 13.1 and use this to check on the sites giving me trouble and it seems that whenever there's a bottlenet, packet losses start to increase when Comcast routes its signals to Level 3 Communications nodes. From there, performance declines through multiple Level 3 nodes. Then there's a jump to a Level 3 Node in Broomfield CO regardless of where the other servers are. This is where the packet loss is usually the highest, and there's always a jump to that node when things go into the dumper.
From Broomfield the trace goes to the ISP of the site I'm trying to connect to. At that point packet loss starts to drop until it's 0 at the site.
That's the most sense I can make out of the VisualRoute traces, anyway.
Now I realize this is "Cybermonday" and traffic is expected to be high, especially after 11:00am EST when the folks on the west coast start to go online at 8:00am PST. Sure enough it's gotten worse. But the problem I've described above has been pretty constant to a lesser degree and I often have to stop my browser and press "Reload" a few times to try to get a faster connection. Sometimes that works, sometimes not.
I see other people adding their "modem parameters" to their posts, so here are mine:

I also see that other people include "Traceroute" information. Here's a typical trace with VisualRoute, trying to connect to www.monoprice.com. Note that sackett.cyberverse.net is the Level 3 server Broomfield CO
Thanks for your time,

I am duplicating your Level 3 losses and the losses at cyberverse flint-sackett, and I never reach the monoprice site. Is the site down?
Can you contact the webmmaster of the site you are trying to reach (monoprice) and get them to troubleshoot the issue for you?
It turns out there are problems at monoprice too. I do have this problem with other sites but in this case monoprice has made things even worse.
This morning they posted a banner message saying there would be delays in shipping because they were in the process of moving to a new warehouse.
Later they said they had to perform emergency maintenance from 10:00am - 10:10am PST to resolve "constant problems with our ordering page" or something like that. They weren't back up by 10:15am PST so I stopped trying.
Now it's about 7:00pm EST, 4:00pm PST. The banner message on their website now reads:
"Due to the heavy order volume, we are experiencing delays on fulfilling most of the orders. We are temporarily unable to accept any new orders with expedited guaranteed shipping options at this time until further notice. We are doing our best to ship out all the orders ASAP. We truly apologize for the delay and any inconvenience this may cause you."
This could be a combination of problems including the fact that it's "CyberMonday" and buying volume is high everywhere. I don't believe the "new warehouse" story, but that's just my opinion.
I'm not going to use monoprice to troubleshoot the other problems I was having. Too many variables with them.
UPDATE 7:00pm EST. I was able to complete an order with monoprice, though I had to reload the ordering pages many times. If you haven't already, give them a try now.
Have a good one,
Big Al Mintaka
not familiar with VisualTrace, does the trace you posted show that you lost 10 packets on the first hop out of your house?
It would be interesting to see a post of a trace to yahoo and perhaps one to another site that you are having an issue with.
Also be nice to see an extended ping to that first IP address in your visual trace from above.
