Googlebot is the Google crawler that prowls this site and looks at the pages, it made a visit when the site was offline and being repaired, fortunately it visits most days so the description should be back to normal soon.
I find the googlebot bizzare sometimes though. I'm waiting for the cached version of one of my sites to reflect the current site and it's been a month at least since the change. I know there's a huge number of pages on the web but I'm sure the bot has visited many other pages on the same and related sites. Mind you, I'm always baffled how people manage to do searches that yield decent results.
