[Pdns-users] ZoneToCache for root zone not working

I am having trouble in getting zonetocache working for the root zone. I
am using PowerDNS Recursor 4.6.0.

I have following in my /etc/powerdns/recursor.lua configuration:

zoneToCache(".", "url", "https://www.internic.net/domain/root.zone", {
refreshPeriod = 0 })

When I start the server I get the following message in the logs:

Dec 21 09:17:13 server.nayatel.com pdns-recursor[19209]: msg="Loaded
zone into cache" subsystem="ztc" level=0 ts="1640060233.959"
refresh="0" zone="."

But when I do dig for the records in the root.zone I get high Query
time. On subsequent queries I get 0 msec time which means it was cached
after I did query for the record.

$ dig b.nic.aaa

;; omitting output

b.nic.aaa. 86400 IN A

;; Query time: 512 msec
