How do I determine what caused my Data-use spike?

I am a 74 y/o retiree with reasonably high computer literacy. My computer use is not highly variable but out of the blue, I have been assessed with a spike in usage, and throttling.

I reacted immediately by initiating a 'booster' so as to continue my very necessary access to the internet, but I am still throttled back to unacceptable speeds. My medical conditions require swift contact with medical professionals and family. 

I need to know just what caused the spike, so as to prevent it reoccurring; if indeed it was caused by me.

This did happen once before, but, as it was with only a day or two from the end of the billing period, I accepted it without question. This time it was in week one of a billing cycle, and that is mysterious.

Was this helpful?

  • Yes it was, thank you
  • No, I still need help

Hi @Genealogist 


The first thing I would do is change your WiFI password in your modem and then match that with any devices that use that WiFi.


You are intitles to 3 free top-ups per year with home broadband.


More information on how to do that is available at 


Contacting support directly might help find why you useds the data.

My body's absorbed so much hand sanitizer that when I pee, it cleans the toilet. 🙂
