Honestly, can someone explain why it took so long?
I mean, you can get IPv6 on a bunch of low-end budget VPSs. Why couldn't Amazon do it? And why cant GCE do it?
Is it a lot of work?

Notably, even low-level stuff may still be difficult to make with IPv6. For example, Linux supports IP equal-cost multipath routing for IPv6 since 2012. Quagga, a popular routing daemon, still doesn't support that. BIRD, another open-source routing daemon, just got partial support for it this year. If your network is relying on this, it's an additional burden to deploy IPv6.

Granted, that isn't necessarily a pre-requisite for going dual stack (aka: just attaching a v6 address to a machine), but it shows the fun problems you run into.
