Este es el último (o penúltimo más bien :-) ) paso en el ciclo de la 
rotación de la KSK.

Si bien ya nadie debería depender de esto para nada, obsérvese que 
cambia el key-tag de la KSK-2010.

> Dear colleagues,
> A few moments ago, at 1400 UTC today, 11 January 2019, ICANN's root 
> zone management partner, Verisign, published root zone serial number 
> 2019011100 with the RFC 5011 REVOKE bit set. As a result, KSK-2010's 
> key tag has changed from 19036 to 19164. In addition, the root DNSKEY 
> RRset is now signed with two KSKs: the current KSK (KSK-2017) as well 
> as the former KSK (KSK-2010). The second signature is required by RFC 
> 5011 to prove possession of KSK-2010's private key to assert the 
> revocation. This second signature makes the response to a query for 
> the root zone's DNSKEY RRset increase in size from 1414 bytes to 1425 
> bytes.
> We don't expect any operational issues from this change. The DNSKEY 
> RRset size increase is small, and other zones currently publish 
> considerably larger apex DNSKEY RRsets without apparent issue. In 
> addition, because KSK-2010 has not been used for signing since the 
> root KSK rollover to KSK-2017 on 11 October 2018, no DNSSEC validators
