The Mac Mini that hosts xom.nu, The Cafes, and Mokka mit Schlag seems to have died. I'll bring them back as soon as I can, but it may take a couple of days.
Update: it appears the problem is simply a dead power brick. I swapped in the power adapter from my wife's Mini and the server booted right up. However since I doubt she'll be willing to go computerless until I can find a new brick, www.elharo.com will likely go down again shortly. The server should be back up more permanently just as soon as I can find a new power brick or move the sites to a shared host, whichever comes first.
