Hi Fabian, welcome to the IC community. I see you already posted in the thread on Node Provider Proposals, where discussion and communication takes place on Node Provider Proposals. Feel free to post any questions that you have in that thread. Also note that currently the IC network has reached target topology, which means that the current network has achieved the decentralization targets and no more new node machines are required. But with the IC network continuing to grow the community might decide to update the target topology and allow for more node machines to be onboarded in the future.
