I think the point of many on this list is, they are a transit provider,
not a security provider. They should not need to filter your traffic,
that should be up to the end user/edge network to decide for themselves.
Additionally, content filtering is great for those type of end-user
folks, as this solution wouldn't be so difficult to scale for their
traffic volumes. However, trying to content filter a transit provider is
probably not a great idea.

I may be off base here. Can't an ips look at the traffic; say on 443
and figure out whether the traffic is malicious or not? If so then let
it filter it. I know IPS's aren't perfect, but, i would prefer this
router be taken, if available and sensible including network outage or
DDOS, than a hard block. A quick block to mitigate and then an IPS rule
installed AFTER through investigation of the traffic could lessen the
load and maybe eliminate the malicious traffic without having to use a
hard block. I know most here prefer not to..i am not saying this is a
let's block is all thread, just trying to throw out something i do not
see being discussed.
