In some cases, your device may pull from cache instead of loading from the CDN, as the file is already gone there.

Outside Discord app? No. It's not possible.

*Unless you visited that link before channel deletion.

it's region cached server-side for a while. e.g. if you upload a file, view the file from london, and then delete the files. london users will be able to view the file for a short while. if someone in america then tries to view the file using the same link, they'll find that the file 404's

Could you tell me whether this is cdn.discordapp.com or media.discordapp.net ?

I can verify that this is a legitimate issue. I have files retaining from several years ago in hundreds of deleted Discord channels. Yes, the server cache & browser cache & especially the region where you access the server matters, but this information should not be held for several years after deletion.

cdn.discordapp.com

This is actually a Discord infrastructure limitation. It is something we've been tracking internally and will likely eventually be fixed, but as it is not related to the API or Bots I've closed this issue.

Hello, this issue has been opened 2.5 years ago and still exist.

Ok it may be not related to the api.
But it exists.
File, uploaded and shared by mistake, which can contain sensitive data, is undeletable from cdn.discordapp.com after being deleted from channel or after deleting a channel, or it takes too long to get deleted. It's a critical operational security issue.

Are you value our privacy? Because it does not look so.

I also noticed this is an issue with GC's too, I often like to add people to a GC but when someone I add spams stuff we don't like or isn't acceptable, I have to delete the GC so we aren't associated with it. When I leave a GC and I am the last member to leave. Why aren't the attachments deleted? It also makes me concerned that the messages aren't deleted too, when obviously it makes sense to think that they should be when noone is left in there.
