Why do we try to build a connected world?
• It’s a good thing to do?• For the love of technology?• For the challenge?• To connect people?• To assure that everyone has access to the same
information?• For convenience?• Some other reason(s)?

Why? For me…
…the more connected we are, I believe, the more we realize how much we are all actually alike.
I think the world needs this.

The connected world
Whatever your motive may be for building the Internet, yourwork is important on a global scale

Our strategy and what we’ve learned
The most important thing is
ListenThen
Be respectful and Never assume

• After all that work and all those years… What’s left?• Generally speaking two big problems left:1. Areas with small populations2. Areas that are distant from the “big pipes”
It’s getting better, but how do we solve this?First, here’s some relatively recent progress…
Are we done yet?

• Lack of accessible bandwidth and competition between service providers.
• Lack of stability. The network goes down often.• Challenges with navigating Internet administrative
processes (obtaining address space, ASN, etc.).• Network security issues.• Issues with reliable power and other infrastructure items
(air conditioning, dust, moisture, cabling, people, etc.).

• Lack of terrestrial fiber.• High cost of telecommunications and network
equipment that are exacerbated by high import duties, taxes (such as VAT) and additional charges (storage, transaction fees, etc.) that are assessed in order to import hardware.
• Difficult regulatory environments and regulatory barriers• Poorly structured campus, government and/or corporate
networks.

• Excessive dependence on external sources of funding.• Lack of sustainable funding models to cover operating costs.• Lack of well-structured government models for education
and research.• Lack of national or regional cooperation.• Many countries need stronger national leadership to push
for policies of open access Internet that supports education and investigation.

Now how to get connectivity to the least-connectedareas?

Imaging a world that’s “100% Connected”
First of all… Is this something that everyone wants?
I don’t have an answer…
Can people pay for these services? Will they be willing?

Looking ahead
• It looks like the network is coming… Way way orthe other?
• All this data still needs to be moved regionally. • What we build now affects how these new
technologies will work in the future.
