I think it’s implied that it’s been zero days since the underlying cause of some such problem turned out to be DNS related. The number zero being hard coded implies that the root of the problem is always DNS. But, let’s give MTU its due.

Lately, MTU has gotten up my list of things to check when stuff goes down.

It seems carriers can't get their MTUs straight as of late, especially on MPLS links...

I really thought we had this figured out 20 years ago...
