Unreachable sites

A few days ago, I couldn't reach ieee-denver.org from my office in Denver, and today I can't reach businessinsider.com. Here's the traceroute:

I have these problems all the time in Denver, but I never had such issues in California.

Re: Unreachable sites

Judging from the trace, this appears to be a problem coming into "datapipe.net", a hosting provider. As you can see from your posted trace, the packets get stopped at the Datapipe device with address 64.27.127.149, looping until the TTL expires. Either way, I do not THINK this would be a Comcast issue. I've posted a trace to "businessinsider.com" below, with a resolved IP that is the same as the one you got. It is loading fine for me.
