Tell HN: Cloudflare silently injects its analytics when you switch nameservers

94 pointsby stagastoday at 5:49 PM18 commentsview on HN

A few hours ago I switched my nameservers to Cloudflare in order to enable R2 bucket serving through my own subdomain, and I found out that it silently had injected a JS analytics snippet in my HTML-only JS-free site textlog.cc — I had to go to the Analytics dashboard, Add the site to the analytics and then disable the snippet. I find this approach entirely invasive, you should opt-in to features like that not have to opt-out. Just a warning out there to folks who might not be aware of this.

Yikes! I see this too:

Yes, they add the js if "web analytics" is enabled. I believe I had to manually enable it on my old sites though. Maybe it's enabled by default when adding new domains?

Took me a minute to realise this isn't 1.1.1.1 (which Cloudflare also runs), but their original website DNS hosting service.

Is there an opt-out mechanism at least? CF is burning goodwill in months it built over the last decade.

yep, last website I did was JS free 100% except that pesky cloudflare script

Isn't this well known when using CF as a proxy? Not sure how they would provide traffic / DDoS telemetry otherwise.

You left out the part about how you use them as a reverse proxy, which is decoupled from DNS. One is coincidental; the other required.

If they can inject script, they can also snoop on all your cleartext traffic without you knowing....

To add to your experience: It was also very hard, for me, to find the setting that disables this JavaScript.

Surprise! The man in the middle man-in-the-middles! This is only the beginning, when you’ll get used to this they’ll do worse and worse, enshittification, remember?
