I wonder if the Time To Live (TTL) has been changed?
When a query for a DNS record is made to a non-authoritative server and it isn’t cached.
The non-authoritative server makes a query to the authoritative server. When the
authoritative server sends its response it tells the non-authoritative server how long to
cache the response.
The TTL can be found in the SOA record which can be queried from the authoritative server
using a tool called “dig”. Dig is a much more capable and feature rich tool than nslookup
and can be found on most Linux distributions.

DNS at ucsd.edu, a half hour or so when I query the Google DNS, it depends.
Strange that they didn't show up if you didn't make a mistake. Try it a second
time, it will tell you or the same entry was already there,
and refuses to do it in that case, at least with the old one.

I made some DNS changes to my subdomain yesterday
and around 2 hours later they showed up in DNS when I used nslookup. I later made some
more amendments but it's now 24 hours later and they still don't show.
Are the changes transferred in batches? if so what is the update frequency?
Thanks
