The loss of local content
It’s interesting to me that we’ve come so far from where we started when looking at the landscape of the Internet. As originally built, content was hosted locally and it was a benefit to obtain it at a distance (over the Internet). Now, all content is hosted in a few locations to be delivered everywhere; nothing is local. We no longer care about network efficiencies.
Case in point, Comcast (Xfinity) sent an email, this morning, to their customers regarding their storm ready website. This link was sent to Xfinity customers for the use of Xfinity users that are, highly likely, sitting on the Xfinity network. These users are local to that network and have no real need to cross any Internet boundaries (they, effectively, wouldn’t be on the Internet since they wouldn’t be leaving the Xfinity network!). This content, however, might need to be accessed by a customer that’s not on the Xfinity network (a mobile user) and, thus, it would be good to have access from the Internet to this content. Again, not a problem… this is something that happens every day. Here’s what I discovered when I did a little research:

Do you see what I see? Xfinity isn’t hosting their content locally within their own network, they are hosting it on Rackspace’s infrastructure! So any interruption in the Internet connections connecting Xfinity to the rest of the world will yield their own content unavailable on their own network. Anyone else see a problem with this?
Hosting content at home
I guess it’s no surprise that Comcast also does not allow someone to stand up their own server from their home to serve their own content over their Xfinity connection (Verizon Fios does not have this restriction). Since they don’t host their own content, why should anyone else want to? If I wanted to serve up content for my neighborhood, which is likely all using Xfinity Internet connectivity, I would be breaking my terms of service to do it even though it would mean faster access to the content, higher availability, less cost, and better resiliency during disasters.
But this isn’t something people really think about, now days, when everything is on Facebook or other social media outlets being hosted everywhere but where you are.
