It's good for everyone -- if you are an ISP with 35%+ of your traffic coming from Netflix, you might be begging for these boxes in your network.

Yup, as an ISP owner, I can tell you 70-75% of my traffic come through GGC, for every 1gbps traffic from cache nodes 100mbps on average is pulled from the internet. Even with GGC nodes, it's still very expensive, BW-wise.

  I saw another comment on here in the distant past that said an ISP owner decided to pull out the GGC boxes because they would sync vast amounts of data (largely YouTube IIRC) and it wasn't worth it bandwdith wise for them. It sounds like 10:1 is a decent saving but still objectively a lot of data.

    You can't survive as an ISP if you don't have GGC nodes or directly peered with google DC. If your customer wants to watch youtube videos and you serve them through internet only, which will either mean you will have to buy more BW (not financially sustainable) or you will have to cap youtube traffic resulting in inferior user experience and a customer leaving your service. Or just ban youtube - might as well stop running an ISP. The best solution is to peer with their DC - let them do the heavy lifting and you can pull from their cache, then you can chuck the GGC nodes. Google is building a small DC close to our NOC - which means lots of saving for us and a better experience for our customers. We can see us chucking the nodes or in this case, we most likely have to give it back to them or something - they are very expensive and large supermicro servers. 10:1 is not a lot if you are serving a lot of traffic. For 50gbps, thats 5gbps bw - that's a lot of bw for free service - we don't cap youtube traffic (users likely to watch high res 1080p, 4k videos nowadays), we can't sell youtube traffic (license agreement from google) - so as far as ISPs are concerned its pissing away money. To be honest services like youtube, facebook and Netflix, even with their on-premise cache solution are a huge headache and expense for ISPs - it's not just the BW, rack-space, distribution switches, power, they all add up. There is a reason why Google with all their expertise, knowledge, money and influence can't even make a dent in their ISP business - because even with all their money - it insanely expensive when you try to cover most of the country.

        If all the big players do it, you really don't have a choice.
