Re: [public-dns-discuss] DNS Slow to update for domain

[Yunhong Gu]

It is the TTL of the old record, NOT that new one, that decides how long the old record will stay in cache. In addition, if you changes name server, the delegation record from the parent zone can also send the query to the old name server before its own TTL expires.

Anyway, we have an upper threshold of 6 hours for caching, so your change should have been effective on 8.8.8.8 by now.

Hey There Guys,

Any ideas why minifigs.me hasn't updated yet on Google DNS?

C:\Users\Matt>nslookup minifigs.me 8.8.8.8

Server:  google-public-dns-a.google.com

Address:  8.8.8.8

Non-authoritative answer:

Name:    minifigs.me

Address:  63.141.244.218

C:\Users\Matt>nslookup minifigs.me 208.67.222.222

Server:  resolver1.opendns.com

Address:  208.67.222.222

Non-authoritative answer:

Name:    minifigs.me

Address:  198.245.63.153

Should be the one got from OpenDNS 

The DNS was updated at least 30+ minutes ago and the domain has a TTL of 300.

Any information would be helpful,

Regards,

Matt
