No he visto ningúna noticia al respecto aún pero este servicio de dns ha sido descontinuado. Al entrar en su web
The dns0.eu service has been discontinued. We would have liked to keep it running, but it was not sustainable for us in terms of time and resources.We recommend switching to DNS4EU or NextDNS.
Por ahora parece que sigue resolviendo pero si lo estais usando es momento de cambiar
