Everything I’ve seen on it indicates it is and @Stuart Bowman and @hzrd149 are working together. Furthermore, you can use satellite with a blossom drive Frontend
I assume it is under development until notice in contrary.
I'll change my tool to talk to generic Blossom once Sattelite switches.
Seems to work fine now although if I include the filetype on the end of the filehash it gives me a 301 response with the location response header set to the same url without the filetype. Don't see why that's necessary?
