In our market, most customers that put all their faith and slippers in
Ookla have no qualms with choosing a random speed test server on the
Ookla network, with no regard as to whether that server is on-net or
off-net for their ISP, how that server is maintained, how much bandwidth
capacity it has, how it was deployed, its hardware sources, how busy it
is, how much of its bandwidth it can actually exhaust, how traffic
routes to/from it, e.t.c.

Whatever the result, the speed test server or the Ookla network is NEVER
at fault. So now, an ISP in the African market has to explain why a
speed test server on some unknown network in Feira de Santana is
claiming that the customer is not getting what they paid for?

Then again, we all need reasons to wake up in the morning :-)...

Personally, I don't think the content networks and CDN's should focus on
developing yet-another-speed-test-server, because then they are just
pushing the problem back to the ISP. I believe they should better spend
their time:

  * Delivering as-near-to 100% of all of their services to all regions,
    cities, data centres as they possibly can.

  * Providing tools for network operators as well as their consumers
    that are biased toward the expected quality of experience, rather
    than how fast their bandwidth is. A 5Gbps link full of packet loss
    does not a service make - but what does that translate into for the
    type of service the content network or CDN is delivering?

Mark.
