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

       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
