Вводная.  У вас ресурс со средней посещаемостью.  Его ddos-ят http get 
flood-ом.

Задача.  Нужно обеспечить баланс между скоростью ответа сервера и 
доступностью его для пользователей.

Граничные условия.  Ставить 100 серверов или банить сразу AS недопустимо.

Предложите решение лучше чем фильтрация по атакующему ip.
