Does your internet feel slower in the evenings or on weekends? This Python script downloads a 3MB file every 5 minutes to log your download speed in a CSV file. You can change the frequency or choose a different file by editing the script.
### Internet speed test script for Python 2.6+
###
### This runs continuously downloading the test file every 5 minutes to generate
### a csv file that you can use to generate a scatter chart in Excel.

try:

Download speedtest.py
You will find the output file in C:\users\username on Windows, or in /home/username on Linux. It should look like this:
Time,Speed (MB/s)
