After a week and a half after sending an email to FreeDNS I finally got an answer today, at around 5AM. They've enable indexing on the site.
This means that this blog will be visited by GoogleBot and it will appear on Google search.

66.249.64.36 - - [22/Jan/2014:16:45:39 +0200] "GET /category/rpi.html HTTP/1.1" 200 3664 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)"

Also, today I had my first downtime. It was my ISP's fault, not RPi's. The Pi is running well, as you can see from this image.

I think that's all for today. No fancy update, nothing new to say beside Google indexing.
