One of our DNS servers just had incorrect data cached for google.com and
www.google.com:

dwhite at quark:~$ dig www.google.com

;; QUESTION SECTION:
;www.google.com.            IN  A

;; ANSWER SECTION:
www.google.com.     24  IN  A   201.130.208.23
www.google.com.     24  IN  A   201.130.208.44
www.google.com.     24  IN  A   201.130.208.34
www.google.com.     24  IN  A   201.130.208.45
www.google.com.     24  IN  A   201.130.208.29
www.google.com.     24  IN  A   201.130.208.30
www.google.com.     24  IN  A   201.130.208.53
www.google.com.     24  IN  A   201.130.208.38
www.google.com.     24  IN  A   201.130.208.19
www.google.com.     24  IN  A   201.130.208.49
www.google.com.     24  IN  A   201.130.208.59
www.google.com.     24  IN  A   201.130.208.57
www.google.com.     24  IN  A   201.130.208.27
www.google.com.     24  IN  A   201.130.208.42
www.google.com.     24  IN  A   201.130.208.15

After the 24 second cache timeout, the correct (google space) IPs
populated:

;; ANSWER SECTION:
google.com.     138 IN  A   74.125.227.104

google.com.     138 IN  A   74.125.227.99

I did not notice this on any other DNS servers.
