Hi, apologies for any mistakes, this is my first github interaction.
Thanks for the script, it works brilliantly for logging broadband downtime to send to a difficult ISP.

One change I made locally was to report when the logging started in the reporting 'downtime' mode call

:)

If I understand the arguments correctly:

  • internet.py monitor begins monitoring for downtime, writing the results to data.csv
  • internet.py downtime reads from data.csv and prints the total downtime.

@FelesMala - can you share the logging-start-time change you made?

This script does exactly what I want to do. Has anyone made this run in the background and logging without user interaction?
