Eco-friendly Webhosting

Montag Jul 30, 2007

Since a dedicated server easily draws 5000 KWh electrical energy for power and cooling, which is (at least for the german energy mix) equivalent to four tons of carbon dioxide emissions, everybody should have a second thought on how much CO2 his or her web presence produces.

Just like Car Pooling, shared webhosting can save a lot of energy. But if we share a server with somebody else, how can we find out how many nighbours we have to calculate our carbon footprint? The answer: http://www.myipneighbors.com/

Let's see:

  • www.systemhelden.com seems to live on a decicated server, since it is sharing its IP address with www.systemhelden.de only. But: systemhelden.com is running on a Solaris Container, so we are not using a physical server here.
  • One Shared Domain at Strato (that according to Strato only consumes just 1KWh per year) shares the IP address with 700-800 other domains. Combine that with many IP adresses configured in one server, and you get many thousand domains served from one server alone.
  • Our Sun EcoTour Blog shares the server with 17 other domains. Not bad. We just have to make sure to buy enough CO2 neutral energy to feed the Sun EcoRider and the web page.

Hi Rolf, my private Domain has 653 neighbours, so I guess I can sleep calmly :). Now, try looking up Google.com on myipneighbours.com. This is weird: You'll find 31 very strange neighbours... Cheers, Constantin
