There's a "Signal deanonymized" thing going around:

Stay calm. Deep breaths.

👉 while this is a real consideration, the only thing the attacker gets from this is a very rough (kilometers or tens of kilometers radius) location

👉 other communication platforms that use any kind of caching CDN to deliver attachments are just as affected

👉 you almost certainly should continue to use Signal, unless you specifically know that this is a big problem for you.

@rysiek It seems that Cloudflare has only 6 data centers in Germany. There is a single data center in all of North Rhine-Westphalia with its 18 million people. Yes, this isn’t exactly impressive position pinpointing.

I guess somebody on the run who doesn’t want to disclose which country they are in would be concerned about this issue. Then again, they probably wouldn’t want to expose their real IP address to the Signal infrastructure in the first place.
