Came across this site when I googled "How to test internet speed over time". The reason for doing this was as of last weekend, 3-24,25-18, I had issues with download speed in the evenings. Of course, I did what seems to be the obvious thing we do these days, and that was to unplug the modem/router and retest speed. I have a 20mb down/ 1.5mb up plan. I had routinely received between 17-19 down, and 1.4-1.5 up since upgrading a couple years ago through Fair Point (now "Consolidated Communications"). I went from regular dsl, to the "bonded" version.
So, back to last weekend.
I could not for the life of me get my download speed back to normal Saturday night. But when I checked Sunday morning, it had returned to what I had before. So I thought, good, fixed. Then came Sunday evening. Same thing, download speeds of around 1 to 3mb. Hell, my upload speed was greater! Hence my search to test my speed over time.
After playing around and testing with this website, I finally figured out the best settings to achieve what was showing for speeds on other test sites. I chose the closet server, in my case NY. Then made sure to have multithread activated. Also, creating an account allowed me to test every 10 minutes at 200 times. With no account, the most you can test for is 50 times. After a week of testing, I'm able to prove that after 7pm, my download goes to shit. At around 6am the following morning, it returns to normal.
After testing for the week:
As you can see, I'm definitely being throttled. I called Consolidated Communications Friday morning from work. I explained that I was losing my download speed in the evenings and have proof. The lady said I should call when I was having the problem. I said I tried, but the internet phone number that used to be 24/7 through Fair Point, was now telling me that the office was closed and to call between the hours of 8:30am to 5PM. She stated that the internet trouble shooting was still 24/7 and gave me a number to call. I got home late last night and went straight to bed.
Today, Saturday, I will call armed with my proof of throttling. Stay tuned for my update.
Called Saturday evening, and they ran some tests. I was told that a ticket was created, and they are scheduled to come Monday. The tech put into my notes that this issue needs to be checked between the hours of 7pm and 6am in order to test my line when the problems have been occurring. I will post back when and if this problem gets resolved. The tech I spoke with said he had seen this problem before, and it was someone "stealing" bandwidth. If that was the case, and even possible, I wouldn't think that it would happen at a set time every day of the week. I still believe this is a case of network throttling, and that my ISP's algorithm to engage this has somehow lowered my bandwidth to a level that was obvious to me. If it were lowered by only 3 or 4mb, I probably wouldn't have noticed, and not started my "investigation".
