Can someone from Akamai report as to what happened?  I did not see any 
notice on EdgeControl but I did get email from my auto-alerts set up at 
Akamai as follows:
-------------------------------
NAME:        DNS failure
TYPE:        Origin DNS Failure
SERVICE:     HTTP Content Delivery
START TIME:  Wed, Dec 3, 12:42 GMT 2008
STOP TIME:   Wed, Dec 3, 12:50 GMT 2008

DATA:
       CP Code:                     32023
       CP Code Description:         WAA
       Hits:                        53
       Errors:                      5
       Alert Condition (% Errors):  8
       Alert Threshold:             1
       Edge IP:                     0.0.0.0

DESCRIPTION:
The Origin DNS Failure Alert indicates errors when Akamai edge servers are 
unable
to reach the origin server because they're unable to resolve the DNS name.
--------------------------------

So I'm curious as to what happened.

Thanks,
Hank
