This URL doesn't and can't resolve: the "!" character isn't authorized
in the DNS system and cannot currently be converted using IDNA
(international DNS encoding).

www.speedy.com, however, does resolve: it's a french company that is
in the "quick car fix" business (tires, exhausts, etc.).

Do you have a capture of the faulty packets ?

Good luck,
