server instances

Hi guys

Does anyone know what happened to server instances started with Cxxxxxxx?

I live in western europe (Portugal) and for the last few months been playing mainly in those server instances because the instances Hxxxxxxx and Gxxxxxxx have such an awful netcode that are basically unplayable. A really really bad experience to play for me. Only Cxxxxxxx instances are a reasonable experience to play but recently, since last friday or so, the instances are no more.
