I haven't read anywhere that they failed. Isn't the timeline:

- Akamai mitigates attack just fine

- After the attack is over, Akamai does the cost/benefit analysis and decides to stop providing the free service.

The attack was ongoing when Akami gave Brian Krebs 2 hours to find alternate hosting.

The attack showed no signs of waning as the day wore on. Some indications suggest it may have grown stronger. At 4 pm, Akamai gave Krebs two hours' notice that it would no longer assume the considerable cost of defending KrebsOnSecurity.
