Matt Cutts, a Googler covering SEO, blogs that the BigDaddy switchover is nearly complete:

“We’re down to just 1-2 data centers left in the switchover to Bigdaddy. It’s possible that the Bigdaddy switchover will be complete in the next week or two. Just as a reminder, Bigdaddy is a software upgrade to Google’s infrastructure that provides the framework for a lot of improvements to core search quality in the coming months (smarter redirect handling, improved canonicalization, etc.). A team of dedicated people has worked very hard on this change; props to them for the code, sweat, and hours they’ve put into it. ”

Well, that’s good news. With GoDaddy gone to Microsoft, BigDaddy on the way, whatever happened to SugarDaddy? Maybe Big will be the daddy of them all.
