ADSL Cap Delay

Up until a few months ago, we only had 20GB bandwidth per month at my flat. This meant that we could not make heavy use of the internet during the duration of the month.

We are on a plan that caps the internet speed down 64kbit/s when you exceed the monthly limit. However there seems to be an approximately 24 hour delay between going over the bandwidth limit, and getting capped.

Lets do a little math.

  • time = 24 hours = 24 x 60 x 60 seconds
  • internet speed = 800 kb/s

24 x 60 x 60 x 800 = 69120000 kb = 65.9GB

Thats right, I can potentially more than tripple my bandwidth allowance by saving up all the large downloads until the last day of the billing month.

I tested out this theory a couple months ago and managed to download 36GB in one day. The only reason this stopped was because I ran out of things to download and I was not at home at the time 🙂
