Your provider has a name for this cost.  It's called "revenue".

I'm trying hard to not be cynical, but a lot of Tier-1 providers are going
to make a killing off SQL-Slapper, since many contracts are on the basis of
total volume, or a flat rate for the first N megabits/sec, plus a hefty
surcharge for bursts above that rate.  So if somebody is on a gigE port,
paying for 400 mbits/sec plus a burst surcharge, the ISP gets rich if the
company has a Slapper burn for the weekend.....

I suspect we won't see any sane filtering policies from ISPs as long as
there's a financial dis-incentive to do so....
