Next to the ISPs that provide the PoPs, the SixXS project uses many existing and well-known software products which we would have had to create if it didn't exist before and wasn't available to us.
Amongst others we really would like to thank the following organizations/products (in alphabetical order):
A great distribution, which we use on the central machine and almost all of the PoPs.
FamFamFam Silk Icons
SixXS Staff are no designers, fortunately there are people who are and who are then also really good at it. Mark James is one of these people and he created the Silk icon set, which is free to use.
For sponsoring hosting of one of the backend machines, the wildcard SSL certificate used by sixxs.net and likely more importantly for allowing Jeroen to spend a lot of time on SixXS.
Used for amongst others the website and parts of the backend.
Thanks to Pim and Paul for a great hosting environment.
Taking care of all the spam that gets send to us.
