It's actually relatively inexpensive to move gear via cargo container. I'd hazard you could move all 10PB of the Internet Archive for less than $25k-50k in shipping costs (~$2k per 40FT container), with labor extra for loading and unloading. (Disclaimer: I have coordinated data center migrations in a previous life)
Although, it's probably more financially efficient for other nations to offer cultural grants for local IA non-profit entities to spin up infra in country and begin mirroring the South SF location.
That would probably be extremely expensive given the fastest way to mirror the IA is with a truck full of hard drives.
