I can think of a few things that some companies don't have that
outsourcing might get them, but speed/performance isn't always going to
be one of them -- just sitting here with a middle-of-the-night thought
or two about it:

- Geographical distribution of the authoritative servers.  (Different
  power grids, data centers, and away from each other in case of natural
  disasters, etc.)
- Network distribution of the authoritative servers.  (Put 'em as close
  to the big backbones and put them on different ones.)
- Professional maintenance from someone who might consider hiring and/or
  contracting to the DNS "big gun" folks who hang around here sometimes
  in a serious crisis for ideas/help.
- Metrics -- if they are having trouble figuring out BIND, an
  outsourcing company is probably going to have gurus on staff who've
  dealt with BIND logging before and can create useful information from
  it for monthly reports and such.

And the biggest reason they probably outsourced it?  

- Now it's someone else's problem and they just lay out cash.  :-)

Don't know.  Those sound reasonable?
