Anyone else seeing this? Or is it common knowledge I just tripped over?
Was just looking into a DNS issue for a customer and noticed Google's DNS was reporting cache times of 9700+ seconds, despite the zone TTL being 3600 seconds.
First, an authoritative server, then Google's answers. Yes, I know Google's answer is different from mine, thus the discovery of the different cache time.

The only way I see them overriding TTL, is using a maximum of 12 hours, and not what the zone specifies, ie, 24 hours.<BR>

Checked a hostname for an IRC server with a TTL of 900 seconds, they honour that.<BR>
<BR>
-tested on unique hostnames no way in hell google would even know about<BR>
they return xxxxxx 43200 IN A xxxxxxx<BR>
whereas others xxxxx 86400 IN A xxxxxxx <-- the correct one.<BR>
<BR>
so, no big deal really.
