@Revertron @L29Ah Basically that, that's just old BIND servers all over the place.
@L29Ah @rf @ru As they "extend" (hum hum...) the IANA root zone, and contrary to their documentation telling they publish "ICANN" TLDs, I suspect they just forgot to sync their list of IANA TLDs "recently", or just decided arbitrarily to drop some, maybe all IDNs? Interesting observation anyway, showing the perils of using "alternate roots".
@L29Ah @rf @ru Maybe just old/misconfigured software?
