For streaming, google have caches in like every ISP network. Also majority of the people watches the latest and same type of content that is mainly served from the homepage, which is easier to cache and serve.
If you have the ipvfoo extension, you can see it in action. (its easier to see with IPv6)

- mysterydip 2y agoI wonder if that's part of the reason for their algorithms to push the same videos to everyone, they're already cached at the edge so it costs them nothing?
- leros 2y agoI would imagine it's an unintended side effect of the "people recently watched this so it's relevant" part of the algorithm.
- kmeisthax 2y agoMore popular works are more likely to be enjoyable to more people. There is no really objective measure of quality for any creative work, and taste doesn't scale, so publishers bias for popularity as it's one of the few things they can understand.
- michaelt 2y ago> taste doesn't scale The motto of so many social networks. Even if they don't know it.
- carlosjobim 2y agoThe majority will enjoy and like whatever is pushed on them. Decades of radio and TV should be enough evidence for this. Music or video is not popular because people like it, but because somebody decided to make it popular by pushing it on people.
- wiseowise 2y ago> taste doesn't scale Wow, I’m going to put this on a wall.
- occz 2y agoI would imagine that's too insignificant to factor into that particular calculation.
- hombre_fatal 2y agoThey’re cached because they’re popular, not popular because they’re cached .

- cloudking 2y agoThis is the correct answer. Caches in local PoPs https://cloud.google.com/cdn/docs/locations https://cloud.google.com/cdn/docs/locations
- miyuru 2y agoThey even have a map. https://peering.google.com/#/infrastructure#edge-nodes https://peering.google.com/#/infrastructure#edge-nodes It also says "Static content that's very popular with the local host's user base, including YouTube and Google Play, is temporarily cached on edge nodes. Google's traffic management systems direct user requests to an edge node that provides the best experience."
- tialaramex 2y agoAlthough note the map is only city addresses. For example the "London" pin is on the notional point where "London" is, ie Charing Cross. There is no giant network interchange at Charing Cross, it's just a convenient place co-ordinate for "London".
- zajio1am 2y agoThere is a big difference between 'caches in ISP networks' and 'caches in public datacenters adjacent to local exchange points'. The first implies preferential treatment from ISPs, the second is commodity available to everybody. Your link implies these local PoPs are more likely the second case.
- phendrenad2 2y agoYes. This is the secret to Netflix's success too. They don't need a CDN, the ISPs do that for them. (Net neutrality what?)
- sambazi 2y agothey run their own cdn. it's arguable cheaper than buying but then again it's also the core business and outsourcing put's the whole operation in danger
- Hikikomori 2y agoWhat? Netflix has their own cdn, they talk about it often.
- phendrenad2 2y agoMy car runs on gas. I don't own my own network of gas stations, but I still have a gas tank that keeps me going.
- Hikikomori 2y ago>What is Netflix Open Connect? Open Connect is the name of the global network that is responsible for delivering Netflix TV shows and movies to our members world-wide. This type of network is typically referred to as a “Content Delivery Network” or “CDN” because its job is to deliver internet-based content (via HTTP/HTTPS) efficiently by bringing the content that people watch close to where they’re watching it. The Open Connect network shares some characteristics with other CDNs, but also has some important differences.
- sophacles 2y agoWhat exactly do you think a CDN is?
- phendrenad2 2y agoOkay I'll answer your low-effort question in case a lot of people, like you, think they know what a CDN is but don't. A CDN is when you set up servers in datacenters around the country and distribute content to them so that your content is closer to your users. What Netflix did is create guidelines for ISPs that want to cache Netflix content at the edge. So Netflix isn't running a CDN themselves, the ISP acts as a CDN.
