The thing is - DHS told us so is the new favourite excuse for operators to
refuse to fix anything that is/or could be broken.

Over last two weeks I have heard the "We have implemented the DHS order" as
the excuse from

- Transport company whose gige transport went from 5ms to 700ms rtt.
- Enterprise IP provider who filtered everything but ICMP/TCP/UDP while
  offering multicast services.
- Two different IP backbones as the explanation of ICMP echo-requests being 
  dropped (the issue was that in reality they were selling multiple 
  100Mbit/sec connections from 155 link).

Of course, the moment one hears the "DHS told us" line, nothing else can be
done.
