@vipermt: Your cable connection looks healthy to me. Nothing wrong with it. The only issues I'm spotting are off of your ISP's network, mainly on the Cogent network which is appearing as some packet loss. Generally it is somewhat normal at that far of a distance, but even then, the ping spike and the dropped latency every here and there is what may be causing a problem.
@modest: Your trace to the servers is pretty much perfect. It looks like your line is on an Interleaved profile, but if only that second hop would have replied I could have noted that for sure.
I'll see if Corey is fine with me setting up a speed test on my account for you guys to use to check at least your download speed to the servers. For the most part the problem may be with the amount of Apache "Worker" threads that are being used. They can get used up rather fast in the free hosting world, though I'm sure Corey is working on a solution to solve this without making Apache consume a ton of resources. I could bring it up with him. It could also be server abuse or unusually high load which Corey is working on getting solved at this very moment.
For now, if you want to at least test download speeds in a basic manner until the time I can get a full blown speed test up (if I can), download this file below and post up what the transfer speed of the file is. It's 20 or so Megabytes big, so it won't last very long. You will need to do a Right Click > Save Target As in order to download this file to see the transfer rates. Clicking it will simply load up a multi-colored JPEG image.
