Apparently verizon's resolvers are being hit with a high number of queries
for sandia.gov (ANY?), for which they've begun refusing queries for
sandia.gov altogether.  These resolvers aren't generally "open" (as far as
I can tell), which means that if these are being used for
amplification/reflection (the latter they have not fixed by sending REFUSED
messages), the target ("source") is verizon's own.

In the mean time, Sandia is inaccessible to legitimate verizon customers.
