There are several papers about how to stop DDoS by using cryptographic puzzles.[1] The core idea is to give the abuser some algorithmic work he has to solve, thereby forcing him to waste processing power, and then to slow him down to a manageable level.[2] That only work if you are the target, and not some intermediary are targeted.
Could it be a solution for the WMF servers?

I was under the (possibly mistaken) impression that the attacker was just flooding the network with traffic?

Cryptographic puzzles are used to slow down an attack, by stopping the attacker from flooding the servers. It will not stop him from flooding the network, but usually that is a rather hard task if he can not establish a connection with the servers.
