Vikings [1] will soon lunch their librehosting service and I asked them at FOSDEM when they will be ready to deliver. They said that they would start in April 2018 with email hosting first and afterwards continue with the librehosting service.
They run on free hardware + FOSS software (Talos 1 and Talos 2) [2]
