The default sources.list entries for all droplets are the us debian mirrors... the speed of update and upgrade increases dramatically if you use the local Dutch servers...
deb http://ftp.nl.debian.org/debian stable main contrib non-free
deb http://ftp.debian.org/debian/ wheezy-updates main contrib non-free
deb http://security.debian.org/ wheezy/updates main contrib non-free
Can these be set as default for these server locations?
