Script kiddies are fun.
Back when I had a Ziggo internet connection I got roughly 10000 attempts to break in to my server every day. With my new XS4ALL connection I get less than 50 attempts a day.
This despite my new connection being 4 times as fast for download and 50 times as fast for upload, and hence a lot more interesting to hack. And despite all my domain names pointing to the new connection.
