The following trace shows the capture of IE trying to load cnn.com. From frame 49 onwards things look fine. I cannot see any tell tale signs of problems. There are some retransmits that popup along the way but nothing that help identify the problem outright. What other areas could I focus on here?

Oh, "some retransmits" is a very polite description. I see almost 10% of all packets require retrasnmission with up to 10 seconds RTO. alt text

Also, there are many HTTP Timeout responses indicating that the server(s) didn't get your data in time. http.response.code == 408

tcp.srcport==54264 and tcp.len gt 0 shows that even small packets don't make it with out excessive retransmissions.

So, somewhere somewhat eats your packets...

Thank you. What are the tell tale signs for the re-transmit reasons?

My apologies - I should rephrase my question - Is there anything else I could look for to see what's 'eating' the packets or does that require looking at the packets at those junctions?

Well, assuming that the rest of the world can browse CNN well I assume that the culprit is close to you. Are you using your iPhone as a hotspot here?

LOL. Yes, I am using my iPhone as a hotspot. I am also with Verizon. As I type this, I'm thinking that this might be a case of throttling?

That's what it is, you probably have exceeded your limit so they slow you down
