Wikimedia Deutschland e.V. is a non-profit association that aims at advancing free knowledge. We support projects creating and spreading free content. One of the most important projects is Wikipedia, the free online encyclopedia. Wikimedia Deutschland has a fast growing office with 48 members of staff in Berlin.

The Toolserver is a very successful project providing an infrastructure in which volunteers and projects can develop and run tools connected to Wikimedia projects. The Toolserver thus is an essential contribution, e.g. for improving the quality of Wikipedia articles, for easier editing or for statistical evaluations. Technically, it consists of servers with replicated databases of all Wikimedia projects, of web servers on which tools can be made available and of login servers with bots and user scripts.

This structure that has grown for years is now reaching its limits for various reasons, which is why migration to a new system is being envisaged. however, the current Toolserver structure will have to remain operational and provide high quality service for at least another year. To ensure the smooth running of the toolserver, Wikimedia Germany is looking for a
