I'm an not an expert webmaster. The thing is I setup my website (http://meemo.com.co) in a Virtual Private Server, in a CentOS installation.
My website has been blocked by some company networks and some ISPs in the country, as I have been informed by some customers. My website doesn't even appear in Google results, even if it's been up for more than a year.
What can be causing the blocking of my website? I've tried to look in black lists to no avail.
