as in: "find some way to keep the customer alive and kicking"

which might be:
1) null route bad destination if no one cares about it
2) acl the traffic upstream if it's not to something you care about
(but need the ip to work)
3) guard/mitigate traffic and redeliver (which has some limitations or did)

all of that is free to 701 customers, yes. if you have to get to step3
more than a few times I'm sure sales will want you to pay, since that
part isn't 'free' to the company.

point being, dropping tcp/80 syn traffic isn't hard, and it's
routinely done at customer request. (or was when I was doing it there)
