: "look, we weren't anticipating such wholesale decimation of websites inflicted by spooked webmasters. Now we're way behind the current reality in terms of indexing all this and recalculating the link graph, etc. Frankly the index is now a mess of 404s, 410s, 301s, canonicals, noindexes and nofollows and it's going to take a while for the our picture of the web to catch-up with the new reality."
With the computing power Google have got they could download the whole web and sort it in an afternoon.
Panda was a completely new ranking system with hundreds of new variables. It was inevitable that there would be bugs.
When Google run tests they use their employees as guinea pigs. Problem is that highly educated geeks from, mainly, wealthy backgrounds don't do searches like the rest of us. This system had to be released onto the public to test it properly and now ironing out those bugs will be a priority but it all takes time and experimentation.
