This affects Signal too

An issue with Cloudflare allows an attacker to find which Cloudflare data center a messaging app used to cache an image, meaning an attacker can obtain the approximate location of Signal, Discord, Twitter/X, and likely other chat app users. In some cases an attacker only needs to send an image across the app, with the target not clicking it, to obtain their location.

Signal, an open-source encrypted messaging service, is widely used by journalists and activists for its privacy features. Internally, the app utilizes two CDNs for serving content: cdn.signal.org (powered by CloudFront) for profile avatars and cdn2.signal.org (powered by Cloudflare) for message attachments.

Another reason to not use Cloudflare. Not that long ago they also "lost the log records" (this incident happened on November 14, 2024). I strongly believe the internet can become better without Cloudflare, especially now basically the whole world is depending on it.

Sorry to see so many people still down vote me. What is wrong with you? The internet has become a joke. Moving all to cloudflare will only make the problem worse.

It is impossible to use most of corpo internet if you block cloudflare. Shit is wild.

Not sure who is down voting you lol

I wish people would respond with a rebuttal so we can move convo forward.

I also have no idea why is down voting me lol. But you are 100% right. Could you imagine in the year 2000 that everything needs to behind Cloudflare in 2025 in order to have a functional internet? This shit is indeed wild.

fuck me lemmy is turning into an absolute reddit-esque cesspool shithole.

i do not understand why people are in here simping for cloudflare (presumably unpaid) do they have money in cloudflare? clearly they don't have a fucking clue whats really going on in the world, but what makes them think they need to actively enforce (ie. downvote people) for pointing out issues with cloudflare??

this is beyond weird.
