KND has fiber available to many places in Nairobi now. Fiber is a physical line that has to be installed but has likely already been run right to your door, now you just need to get it onto your property and into your home/office. The actual connection comes through a DSL line. It's like a phone line and is widely used in the US.

Since this is fiber, there are expensive up front costs to wire your building into the fiber infrastructure.

* UPDATE: The contention ratios have been added.

* UPDATE 2: Unless otherwise noted, all speeds listed are for download and the upload speeds are half that.

While these plans are considerably more expensive than Africa Online, the
important element is that they are in fact dedicated lines and not shared at
all. Also, they have not mentioned any kind of bandwidth caps, which I
specifically requested. So I am to understand that there are none. I have
asked for clarification to that fact.

Personally, I had no idea that the contention ratios were as low as they
were with AOL. I was thinking they¹d be in the order of 1:20 or even higher.
I¹ve also been told, however, that advertised contention ratios are not
always honest. So I am skeptical. If there was a way to test this after
ordering a service, I would definitely want to do that and take the ISP to
task if they were lying.

All that to say, be sure things like this are in your contract. If you care
enough about bandwidth to be reading this post to being with, you care about
your bandwidth and want exactly what is being sold to you, just like myself.
If I¹m signing a contract, I will write in hand on the contract the details
of the plan as I have been sold and have the provider initial next to those
notations.

PS. It¹s a lot harder to fudge the numbers when there is no contention and
it is dedicated. If you don¹t get your full bandwidth, you better believe
I¹d be on my ISP like white on rice.
