Hi, I've used the blackhole iRule https://devcentral.f5.com/articles/v111-dns-blackhole-with-irules, sometimes it blocked the genuine page as well, and i changed few option like instead of ends_with, used eq or contains, then i saw CPU usage is very high. If possible, can we modify the iRule that control the CPU usage and it work properly. Thanks.....Jay
