GNU/Linux traceroute sends UDP by default. Something along the way could
be filtering UDP, so default traceroute may not be indicative.

To better replicate the problem, you can tell traceroute to send TCP
SYNs to the specific port you're trying to reach (443). Run this as root
(it needs raw sockets):

# traceroute -M tcp -p 443 dropbox.com
