I would Akamai Nodes at the same level. A lot of times large sites leverage on Akamai infrastructure for distribution/CDN. Facebook heavily relied on Akamai (esp outside the USA) for a long time, I don't if they still do it. Youtube's very first live streaming of any type (I think it was a concert) was done on Akamai network. Akamai was and still is a very big player. Facebook also has their on-promise nodes, but I don't think they are as ubiquitous.
