Hey @jammerdan!
Thank you for asking and bringing this up!
I just checked https://alpha.transfer.sh and it works fine for me. Maybe a temporary issue on the connection. Can you provide me with a time when you tried the upload?
I can then check our logging to see if there is something of interest.
In terms of storjipfs.com we are working on issues in the connector, that caused files to not be available via the ipfs commands. When that it sorted out, we plan on starting it back up.
