For c) point,
the biggest european countries internet wise are really
well connected. Just restrict to De / Fr / Nl / Uk. Other countries
might be less connected (aka Es, Cz, Ee).
Also lot of ISPs just got their transatlantic links connected to
London, while NL is really the central place of the european internet.
Hence my choice of London and NL. There's plenty of capacity between the
two, as well.

Perhaps.
But hosting servers is one thing. Having human technical help now and
then is necessary as well. There are people to do this in Paris.
