#1) If it was easy they would have done it. Pushing photo deletions up to the CDN is hard without flushing the entire CDN cache. And Facebook has 90 billion photos, so flushing the cache is not an option I guess. (Wrap your head around 90 billion photos. The scale of the problem is huge.)
#2) Anyone with access to the link to the CDN had access to the original photo. So this really doesn't protect someone from viewing your photos you wanted to delete - since if they wanted it before they could have had it.
So ultimately this should not bug you the greatest of all the bad things they have done. The ultimate blame belongs to the person who uploaded the photo to Facebook and then later wanted it deleted.
- dasil003 15y agoYes, but the CDN is not going to cache 90 billion photos indefinitely. Clearly photos being on their for years after deletion, presumably being accessed very rarely, are going to be prime candidates for flushing. In all likelihood these photos are still on the origin server.
