ISP responses to DOS/DDOS attacks for customers

[Wayne Bogan <wbogan () InfoAve Net>]

Is there a standard/general level of response that ISPs should provide when
responding to DOS/DDOS attacks for customer networks. We try to respond and
help any customer with identifying and resolving the problem since most of
our customers don't have the staff to respond appropriately.  How far should
we go?

If this issue has already been addressed, please respond off-list with the
correct direction to search.

Regards,

Wayne
