as was I. (talking about filtering the attack)
Filter like in using the Cisco Guard of sort, to send the good traffic back
to the customers? And that service is <cough>free through vzb?</cough>
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)

Fact: Filtering TCP/80 attacks is a 3 to 4 figure job, sometimes even 5 figure.

I was actually being serious, it's not, it doesn't have to, and in the
case that started this discussion it probably would have been
sufficient to just drop tcp/80 to his link since I would be it's
'business dsl' so he gets an 'SLA' not so he can run a business
critical web service there.
There are services you can buy that are a lot more expensive, but why
would you? if there are options that are more relevant and cheaper...
and in line with what you want. You can certainly pay more if you want
to, I'm not sure that's the smart choice though.

I don't know of any internet access services that provide a SLA against DDoS.

vzb/mci/uunet used to, there is (I believe) still a 'response' SLA,
and there was an SLA for their dos-mitigation service as well...likely
somewhere off: Business Plans, Services, and Solutions | Verizon Business
I was actually talking about an SLA for his link though, not for
dos-mitigation services. There used to be, and still is in some
networks, the thought that consumer grade services were essentially
'un-SLA''d, while 'business class' services had some form of 'uptime'
SLA associated with them.
So, folks that telework often subscribe to 'business dsl' in order to
get more guaranteed availabilty, lack of port filtering, static-ips,
etc.
