According to this, Floating IPs can

be instantly remapped, via the DigitalOcean Control Panel or API, to one of your other Droplets in the same datacenter

What prevents Floating IPs from pointing to Droplets in different data centers?

Because of the inherent workings of Internet routing and the sizes of the blocks allocated to network service providers.

  • Can you elaborate?

    • IPs are allocated in blocks, not individually. This means it's not as trivial as it seems to route a single IP to a different datacenter.

If you are just want load balancer for http/https traffic take a loot at our SaaS Load Balancer https://failovery.com
