:shrug: Yeah it's actually very difficult to launch a very resource intensive product globally all at once. It's not really an excuse, it's just a real problem that Google has. It limits what they can launch and how they can do it, because anything they launch will get used by a huge number of people right away, and everyone expects them to achieve a magical level of performance at that scale. Rolling out region by region based on where data centers are located and what hardware is deployed in them is one possible way to deal with this. I don't think it's good, really, I just think it's unsurprising.
