I'm glad that I could be of help! I consider TestMy.net to be the best speed test program for my purposes, and just don't trust other speed test software as much as TMN. As such, I have not been able to perform a really good speed test for around 4 months now.
I cannot currently think of any other information to provide that I have not posted on that Wild Blue World topic. What must have happened is that someone at ViaSat / Exede noticed modem crashes being generated by TMN. Some type of kludge was added the Exede's modem software to prevent the modem from crashing. Instead, TMN just hangs during a download speed test. I noticed today that even an automatic download speed test will hang. Without my knowledge that this problem is being caused by a bug in Exede's modem software, visually it seems obvious that there is a bug in TMN, but that is not the case. (Screen capture available upon request, but the only thing to see is an incomplete bar graph.)
The person who emailed you was almost certainly a participant on that Wild Blue World topic. Towards the end of the topic, we were having major communication problems. As I argued, if any website crashes Exede's modems, then Exede has the bug, not the website.
It was suggested that I was imagining a corporate conspiracy against TMN. That is not at all what I had in mind. Whoever added that kludge, may not have even known that TMN is a popular speed test website. If Facebook was crashing Exede's modem, that would have gotten fixed rather than just hacked. You'll notice that the iTunes, the topic of the thread, no longer breaks Exede's software.
ViaSat / Exede is not the type of company that would try to intentionally affect speed tests. They are the type of company who would hire a temporary worker with an online Associate's Degree to reduce expenses. (Optional smiley)
Besides wanting TMN to work again, I just didn't want you wasting time looking for a bug that does not exist. I'll be glad to help you in any way that I can, but I need to deal with an Exede service call first. After that, I will begin a concentrated effort to get Exede's TMN bug fixed or at least acknowledged.
