Wrong results Rated 4 out of 5 stars

Hi, tried to contact support@thegreenwebfoundation.org but didn't get an answer.
The add-on delivers wrong results on some pages.
deviantart.com is for example hosted by ntt.net (Japanese).

If I understand it correctly you are guessing the hosting server via IP.
The API on the homepage show DeviantArt as grey.

A bit too harsh

Dear Alex,

We answered after four days, sorry about that.

Regarding the results: as you know the Internet is a very large sphere, and expanding and changing by the minute. We are and will never be always right, but our point is that we are able to show through the addons >90% of all green hosted domains.

In the case of Deviantart, it is hosted in the US by NTT. They might be using a CDN, that can theoretically fool the addon into thinking it is hosted somewhere else. We will look into it.

With kind regards and thanks for using the addon,

Fun but not very useful Rated 4 out of 5 stars

A fun plugin, but not very useful when considering that companies can do so much more than choose a green webhosting to create a better world.

Great transparency Rated 5 out of 5 stars

The Green Web easily shows the user whether websites are hosted using green energy or not. It is a neat way to get some more clues about the sustainability focus of people and organizations.

Using Firefox version 17, on LinuxMint 14 (Ubuntu 12.10) using the cinnamon desktop. It doesn't rely on Cache, Cookies, or offline website data for its positioning does it? Because for privacy I have firefox clear all that at close. None of the other extensions are effected by the clearing.

Problem is related to another addon installed by the user called cubbi.es. We're looking into solving this issue on our end if possible.
