Google's Larry Page: We Are Living in Uncharted Territory
That's what Larry Page said on Google's earnings call, referring to the conjunction of mobile and the cloud. Well, let's chart it then! We need to be thinking about an Internet where 90% of our traffic goes to 70 destinations within 40 miles of us.
I don't know if there is a protocol for staged updating in which you have multiple sites that have certain information and it's replicated on multiple machines, but I'm sure there are some places that have done it. I mean, it makes a whole lot more sense for critical information to be replicated multiple places and when a change is made at any particular spot to propagate it to all others.
"Each server has replicated copies of everything and when changes are made, the changes are made at one of the regional sites then propagated to all the others"
is there such a thing called asynchrounous updating? and if so, is that it?

You might very well be communicating with your friend in China via a connection to a server within 40 miles if Facebook decides to decentralize its infrastructure such that it decides instead of having one huge server and lots of huge amounts of bandwidth for reaching the entire country, they break up their network into the top 200 or 300 regional locations and divert your traffic by ping to your nearest server.
Think about that. Maybe they have one server for everyone in Montana, and one server for the west side of Los Angeles, one server for Manhattan and another for the rest of New York City, one just for Chicago, Kansas City, Denver, Salt Lake Citym etc., then each regional server communicates with the main server - on a much smaller bandwidth than they need when talking to everyone at once - to update the master copy of your information, including in bulk all of the changes they've received for that server.
Each server has replicated copies of everything and when changes are made, the changes are made at one of the regional sites then propagated to all the others, making the network more resilient, since if the national site is down each site can simply send propagated changes to the other sites, and save the changes for the master site until later. Or maybe there is no "master site" it just picks one that the ping time is the fastest for you and hands you to that one.
We're talking traffic Mitch, and profitable traffic at that. Most traffic is cloud, downloads, or video and virtually all of that is directed either at a metro CDN/cache or a local server. Text exchanges don't need bandwidth.
70 destinations within 40 miles of us? Are you thinking here of caching? So if I'm corresponding with my friend in China over Facebook, I'm actually going to be connecting with a server that's within 40 miles of my location?
The whole Amazon.reader debate is a double-stupid. It's stupid to think that there's any e-book buyer who doesn't know Amazon's URL, and it was stupider to let ICANN launch the whole free-form TLD initiative to start with.
Subsidized handsets, rather than locked handsets, should be the focus of regulators. We're not getting good deals, not fostering innovation, and weakening our power as buyers.
50 billion household devices will be on the Internet by 2020, according to Cisco. And we're hearing foreign governments are hacking our infrastructure. Surely our refrigerators are next!
YouTube's move to a partial pay-for-view model could help relieve a dearth of good new content but it could also complicate debates in many parts of the world over payment by content providers for delivery of their material to customers.
Facebook's Graph Search may face some profound challenges and risks, first, because Facebook users haven't been thinking of their posts as product reviews; and second, because Facebook will now have to contend with the social-network equivalent of SEO "gaming" of results.
EU operators are considering joining up to create a pan-European network to reduce competitive overbuild and cost. This might lower costs and focus operators on higher-level, more interesting services.
Many enterprises view high-speed broadband connections as ubiquitous. Yet in about 20 percent of the country, businesses and their employees do not have access to even DSL connections. This shortcoming diminishes enterprises' ability to support their employees.
Skype recently acquired GroupMe, a startup developing tools to make mobile communications simpler. The move underscores dramatic changes in that market, ones that will change how executives communicate.
Microsoft's buy of Skype could revitalize Phone 7, give Microsoft a social, gaming, and collaborative strategy, and spell the end for old-fashioned telco voice. It will also certainly give Google a headache in its Voice, Chat, and even Android strategy!

Software-defined networks, which deliver virtualization functions to enterprise networks, have the potential to dramatically change network design and significantly reduce costs and maintenance.
