RankingLinux.com , that site which, as its name indicates, is a ranking of sites/blogs related to Linux, has been offline since yesterday.

What could have happened? … O_O …
Does anyone know of a site that provides a service similar to RankingLinux?

I would need someone to explain to me how the method that RankingLinux used works (or worked), how did he position the sites / blogs? Etc. The idea is clear, right?
If anyone has any data, ideas, whatever can help us create a similar service, it would be great to get in touch with us.
