Its not a bug with bind.
google.com has weird TTL settings that do not comply with the RFC.
You can only cache it for 5 minutes maximum coz the TTL for it is
only just that.

Ok, bind-9.2.5 is driving me crazy!
Isn't it supposed to cache queries so that if you ask for a domain
once, the next time the answer is picked from the cache?
Just look at these two queries below, you can see the time difference
between them isn't much but the second query returns nothing!
By the way, does squid cache name lookups as well?
Any ideas why this is so?
