Hello Peter,

I don't know if this could be any real help, but anyway I have a slightly
different suggestion, that may be interesting. Years ago we did a DNS-project
that allows to spread a domain to several _different_ ip locations based on the
dns-_requesting_ ip. You may know such a technique from akamai (MS daughter).
In fact we implemented and test-runned it years ago, but did not find any
customer interested (in fact only real big customers _can_ be interested at
all, and we didn't have the "connections"). Anyway the know-how is still here
and can be used to help kernel.org, if interested. The basic idea is, that this
splits costs in running kernel.org to several locations. These locations can
(e.g.) be providers who may have some strategic interests. You may as well come
up with a GNU project of spreading kernel.org mirrors - meaning every provider
be it small or big can have its own mirror, and _only_ his customers (depending
on their IP or his AS) are using it. So if you have a major breakdown at the
primary server, people will get no _new_ pages, but kernel.org itself looks up
throughout all IP-ranges that have a mirror "attached".

What do you think?

Regards,
Stephan von Krawczynski
