I'm know that's strange.... The server on which the problem was is a FTP account I've have at an hosting.
The second is an dedicated server I've at home. So environments are completely different but I repete the problem come and leave without modification of me. So perhaps it's come from the hosting....
Like you I've never have any problem since a long time with the bbapi before this week end.
