If you are paying them, they should be able to police ipv4 udp to some
reasonable baseline.  This is a smart proactive method.

They should also be able to put in an acl to simply block udp source ports
that are problem ... Each of these need to be weighed on customer impact
for blocking source udp 53, ntp, ssdp , chargen , frags..

There is also rtbh.

I would avoid scrubbers, acls and policers and rtbh work.
