Eric Meyer experiences internet access in rural Uganda:
For geosynchronous-satellite internet access, the speed of light become a factor in ping times: just having the signals propagate through a mixture of vacuum and atmosphere chews up approximately half a second of travel time over roughly 89,000 miles (~152,000km).
But that’s not the real connection killer in most cases: packet loss is. After all, these packets are going to orbit and back. Lots of things along those long and lonely signal paths can cause the packets to get dropped. 50% packet loss is not uncommon; 80% is not unexpected.
A local caching server, meant to speed up commonly-requested sites and reduce bandwidth usage, is a “man in the middle”. HTTPS, which by design prevents man-in-the-middle attacks, utterly breaks local caching servers. So I kept waiting and waiting for remote resources, eating into that month’s data cap with every request.
