belgian sites are under turkish hack attack
If you don't have any business with turkye and don't want any business with turkye you should block all traffic from turkye to your website and ask your hoster and ISP to do so.
Maybe that will send a signal to the turkish autorities that want to become part of Europe but are thrown off the european internet because of some turkish ultra nationalist or fundamentalist hackers they refuse to stop - but any other dissident is send to jail.
Turkey is not the first country that is learning that your online image is what you let it to be - or why do think Nigeria prosecuted its online fraud business so hard that nowadays Nigerian fraud is more or less gone. Because everybody was treating everything Nigerian online as online fraud.
