TrueNas Scale - DNS lookups to "update.ixsystems.com" (storjshare.io) every 15 seconds

UPDATE: this seems to be a CNAME for “link.storjshare.io” with a TTL of 13 seconds…
I guess that the Truenas updates are stored in storj and their link system has such a small TTL on purpose.

Hi all - after setting up pi-hole on my network, I noticed that my Scale system is doing DNS lookups for “update.ixsystems.com” (both A an AAAA) every 15 seconds and thus in my top DNS request list.
I switched off Telemetry & Daily Update Check - didn’t change anything.
Is this normal? I find this quite excessive, really.
