Our corporate proxy is categorizing "cdn0.opera-mini.net" as "Proxy Avoidance" and thus is blocking the connection. I guess you are reusing the URL's that's used for Opera Turbo? Might be something you want to look into.

For people who are not getting to see the proper page - are you using any parental filter / anti-virus / corporate firewall etc? If so, which one? This will be usefull info for us if you could share it.

We do and I see that we are blocking some traffic, please contact me directly since I can't disclose the information publicly like this.
