O2 ‘zero-rating’ access to selected public help websites
« on: March 26, 2020, 04:25:36 PM »

Regarding the article

How does O2 make this work? Do they know the many IP addresses of all these websites’ servers -no, presumably, especially because if CDNs. Are they snooping on your access then, pulling metadata from your traffic ? And I wouldn’t be happy about them snooping at L4, at the http level.

Hopefully then you’re using a VPN so as to prevent such possible O2 snooping. You could say a good reason not to use O2 otherwise?

My wife uses EE on her iPhone. Perhaps I need an iOS VPN software component on that machine then?

UPDATE 1:53pm

Just to confirm that O2 zero-rate on a HTTP/SSL domain basis only, which means any third-party content that may be pulled into a website when it’s rendered will still be eating into your data allowance. Most websites pull in remote content via remote CDNs, JQuery, YouTube, Advertising etc. All of that can add up but most web browsers do tend to cache many repeated resources (javascript files etc.) after the first load.
