Thanks for reporting this  nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z. Strange, we were not able to reproduce this. Everything from our media server loads quickly for us from all nostr clients we tried. I believe you and others who reported this, that there's an issue, just can't repro it. Btw, we are not rate limiting anything on the media server and we are not hitting the ceiling in terms of bandwidth. 

Last night we made a change in the way we work with our CDN, based on our feedback. This might fix the issue you reported. Please let us know if it works better now.
