French developers seem to have adopted Hudson enthusiastically. A new article on Hudson by my colleague Romain Linsolas has been published on the influential developpez.com community.
Valtech has been very visible on the European scene regarding Hudson. But it seems that competitors such as Xebia and Octo are also using it now.
Also, this article comes right on the heels of Hudson finally being hosted on Subversion (when the project was created, the only SCM option on dev.java.net was CVS). It will be at last possible to access the repository from behind a firewall! ;-)
I can confirm we are using Hudson at Xebia France. I have been installing and using Hudson on my clients projects since almost a year now.
Right now I don’t see any reason to switch back to another CI solution.
And Eric, thanks for the French translation of Hudson!
