nbn SkyMuster uses a system called Web Page Optimisation (WPO).
Web Page Optimisation is designed to help speed the loading of pages, as you browse.
A downside of WPO is that nbn counts all the data that WPO pre-fetches, including data collected to speed up your page loads even if you never see them.
Some providers (if asked) will disable (turn off) WPO.
You may experience some pages loading a little slower, but for many there is little change in speed.
Disabling WPO will stop the addition of the WPO overhead to your account.
The amount of additional data that WPO uses will vary with the the day to day internet activity of your household.
For those on SkyMuster who are struggling to keep within their account quota, disabling WPO may be something to consider.
*Please note, while all care has been taken in compiling BIRRR documents, we recommend that you check with NBN or your ISP regarding your own connection issues.
