Is that your whole command?  It's pretty obvious when you dig directly
at one of their nsN.criteo.com servers.  Doesn't matter which part of
the label has a capital letter, either.  Compare:

dig widget.criteo.com @ns1.criteo.com -> 1 A,   300s TTL
dig widget.criTeo.com @ns1.criteo.com -> 7 As, 3600s TTL

Someone here observed that they appear to be geo mapping, but the
decision to do that is only being triggered based on a case-sensitive

Independent of Peter's original question, it appears these people need
to be informed that their authority server is broken and to fix it.
