As per PSR2, the static declaration should come after the visibility declaration.

        return self::$instance ?? self::$instance = new static();
    }

    /**
     * @param $hostname
     * @return bool
     */
    public static function validate(string $hostname) : bool
    {
        return self::getInstance()->validator->isValid($hostname);
    }
}
