Hi all,

Not specifically related to this incident, I am wondering if anyone else 
noticed that a.gtld-servers.net (at least nnn1-elsyd3) also had an issue 
last week.

It seems to have stop getting any updates from Tuesday, 18 Feb 2020 
02:32:50 AWST at least until around  Wednesday, 19 Feb 2020 14:30 AWST. 
A few customers reported issues resolving domains they registered after 
the initial time based on the SOA getting returned:

a.gtld-servers.net. nstld.verisign-grs.com. 1581964370 1800 900 604800 86400

Queries for new domains returned a NXDOMAIN like it had not received any 
updates from the SOA serial onwards.
