Re: Patch a key
Depends on the type of DoS-attack. For a DDoS-attack you may be able to add capacity, although that's not a given.
However, DoS can be accomplished even with a single request or action in some instances. Generally, no amount of capacity will help in such cases. Although I have seen a web form that required one server per user - two people using the web form at the same time on the same server caused a DoS-sitution. I suppose that in that case you could just add servers...
