Last September, the library of the University of Bielefeld decided to stop hosting PhysicsOverflow and AskOpenScience by the end of last year. At first, this seemed very unfortunate, but thanks to the initiative of Christian Pietsch http://www.ub.uni-bielefeld.de/~cpietsch/ and the great work of Christian and Polarkernel https://www.physicsoverflow.org/user/polarkernel, we have been able to move smoothly to a server of the Department of Physics of the University of Bielefeld. We are very thankful and happy, that the Dean of the physics department and its IT team allowed and supported this!
Apart from being now at a physics department where we rightfully belong, we are able to keep most advantages we have known from living at the library of the University of Bielefeld, compared to using a commercial hosting provider.
The PhysicsOverflow team wishes a happy and successful year to everybody!
