If I were on a 5 stop tour and my choice was between "hand-delivered by a Backblaze employee" and "left to fate with multiple countries' postal and customs services," I would choose the hand delivery every time. The nearest data center to Kazakhstan is in Amsterdam.

We're talking unreleased songs on that drive and high value assets surrounding the act. Both the sensitive nature of the data as well as the speed of delivery are better handled by having a person fly them in personally.

If it wasn't for the content and that they needed it ASAP I think regular air cargo would've sufficed.
