CNAME record redirect to old A record

In the DNS zone of our domain, we had an A record defined for the subdomain. We deleted the A record for this subdomain and set CNAME for this subdomain. Unfortunately, for 2 weeks some traffic is still being forwarded randomly to the old IP address from the deleted A record or to the new one indicated in the CNAME. We used the Purge Cache tool, but that didn’t help either. How can you solve this problem?

What is the record in question?

Hi sandro,

I have a limit of 2 links in the message so I will use the “[dot]” notation instead of “.”:

Old A record: use[dot]feedink[dot]com -> 145.239.175.48 (TTL Auto)
New CNAME record: use[dot]feedink[dot]com -> d3oi6ntbicnevf.cloudfront.net (TTL Auto, DNS only)

Certainly it is not a matter of local DNS cache, because for example on the same computer it has redirected correctly during the last few days, and yesterday it started to be bad, and today it is correct again.

Resolves fine for me

nslookup use.feedink.com 1.1.1.1
Server:  one.one.one.one
Address:  1.1.1.1
