[Description of nasty DOS attack snipped.]
Needless to say, I did not have any fun today.
Suggestion...
Some people claim that the only way to get rid of professional spammers
is to make it too expensive for them to do business, for example
by charging them a serious "cleanup" fee if they get kicked off for
spamming.
Maybe the same idea logic holds for checking source IP addresses.
If there isn't any visible cost to procrastinating then many sysamdins
will continue to put installing the filters on the back burner.
So how about modifying contracts, including peering agreements, to charge
for DOS problems?
You could charge twice as much (per hour?) if the NOC didn't respond
within some time limit.
