Any post-mortem story?

I wonder why did they let themselves to be DDOSed so easily -- apparently they knew the risks
involved, yet still the moment the download day started their websites went down. There were
some strange glitches as well -- e.g., it was actually offering firefox 2.0.0.14 download
instead of 3.0 for some time, and so on. I wonder if there is an insider story about all that
somewhere on the net. Post-mortem stories are always an interesting read.
