I don't quite follow. Your data is preserved, but the whole point of the CDN is to use URLs in your notes that point to the "stuff." Wouldn't the URLs you created before blossom all stop working? For example, the screenshot in your note is a url to nostr.build.
all the stuff I had uploaded to my Satellite CDN is already up there...
and I can one-click transfer my content to another blossom server
and if/when nostr:npub1lunaq893u4hmtpvqxpk8hfmtkqmm7ggutdtnc4hyuux2skr4ttcqr827lj rugs me, all the media I had uploaded there, all the notes I published referencing the Satellite CDN will just magically continue to work
let's repeat that:
*all the notes I had *already* published, before Blossom even existed, WILL CONTINUE TO FUCKING WORK
Discussion
yes
correct
BUT
once the URL dies, all the information needed to find the file again is there, which means that, even though that URL doesn't work anymore, any blossom-aware client can find the file again
