Neustar operates 271 TLDs. Either they have done some key roll overs, or <br class="">
Viktor missed some Neustar TLDs. ;-)<br class="">

I have all the TLDs covered, so perhaps some did get rolled over,<br class="">
or use keys stronger than 1024 bits.<br class="">
<br class="">
One thing I did not mention (because I only checked now), is that<br class="">
one reason for so many TLDs having similarly aged keys, is that in<br class="">
fact 124 TLDs share the same pair of 1024-bit ZSKs, and 57 of them<br class="">
also share a third 1024-bit ZSK, all present since Oct 2017 ("kid"<br class="">
is a unique database id for each key):<br class="">

Neustar registry teams are aware of the aging keys, technical teams are fully tasked on other projects at this time and we are planning the rollovers on a schedule that will not impact other product commitments.</span><br style="font-family: Menlo-Regular; font-size: 12px;" class="">
