This same thing happens to my server on a much smaller scale. If my memcache were to suddenly think all cached objects needed to be replaced, my server crumbles to it's knees while the db gets hammered.

It is a risk/ tradeoff of highly cached system.

I can only imagine the issues they face at the scale they deal with. So much dynamic content. Crazy.
