#2> There are at least three independent paths (N+2 redundancy) between any two locations on the Google network, helping ensure that traffic continues to flow between these two locations even in the event of a disruption. As a result, with Premium Tier, your traffic is unaffected by a single fiber cut. In many situations, traffic can flow to and from your application without interruption even with two simultaneous fiber cuts.
What does this mean? N+2 redundancy should mean, that even if both go down, then service will not be affected at all, no?

#3TL;DR: New Standard tier level is hot potato routing while existing (now called Premium) tier is cold potato routing.

N+2 usually means one redundancy for normal operations (deploys, maintenance) and one for disruptions. If the disruption happens while there is an ongoing maintenance, you'll be resilient for one event only.

Two fiber cuts in a N+2 network could overload the last remaining path, resulting in some impact on service.

#7I thought I read an article about an online game company who was doing something similar with their users; trying to get their users on their private network as soon as possible. Does anyone else remember that article on HN?

I think this would (or should) be called N+1.
Edit: but you're right, this might be what they mean.

#9Reading this I just got stumped by how many stacks, layers, hardware, technologies, and knowledge incorporated into all of that those bytes needed to travel so I could read them on a laptop across the globe

#10So is this like the app engine price hike debacle a few years ago but with "better" messaging? So "Try Network Service Tiers Today" means "Migrate to Standard Tier today to avoid the massive price increases coming soon"?
But fundamentally they just massively underestimated costs and need to find a way to adjust pricing. With app engine it was very conveniently beta, so they used the end of beta for the price hike. For this, they're having to invent a "Premium" and a "Standard" Tier, and hey guess what, everyone has been using "Premium".
My experience so far with Google has been "Use this now, and we'll have a massive price hike later, if we keep it around at all."
