Google has been making a number of changes and updates recently. They have been testing their new search engine commonly referred to as Google Caffeine around the internet in various forums and discussion sites. We also got a set of new additional features at the current standard Google search site, which is pretty cool.
Early this morning I couldn't even get any Google site to load. Google search was down or extremely slow, almost useless. I couldn't get into Google Adsense, Google Webmaster Tools, or just about any other Google related site. I'm not sure what the problem was. It is very rare that something like that happens to Google.
Then there is also the fact that we are due and almost overdue for a Google Pagerank update. The last one was somewhere around the end of May 2009. Generally Google does a Pagerank update on average of every 3 months. However, I have seen them update in 2 months time up to 6 months. Since it has now going on 4 months since the last update, there have been a number of discussions regarding when it will happen.
I am not really expecting any changes this time around, as I was busy with other projects and didn't have as much time to focus on increasing pagerank.
So it appears as if Google has been up to and busy with a number of changes, improvements, and enhancements recently. We will have to just wait and see what else the big G throws at us, or gives us next.
