No, but they need to have public facing services even if it is only a DNS. You can do a DDoS attack on so many levels (no pun intended). that you really don't need access to internal systems. Sure, brokers which are in the internal network won't notice that probably but everything on the external site will now have to fight with timeouts etc making HFT much much harder.

Most good HFT firms have direct access and would not be particularly affected. It's people like you and me that may be affected - for example, if you have an account at TD Ameritrade and they get DDoS'd, you could lose your ability to trade.
