Other libraries include similar scripts and frameworks such as jQuery UI and the corresponding css. It is notable that google provides both HTTP and HTTPS / SSL versions of these resources.
Google also recently released an updated algorithm to enhance search results, and they are also going to be phasing out Google Product Search in favor of a marketplace where they will make commission and rank products higher based on bids (using the Adwords admin interface). Perhaps those things are also slowing down this giant.
Do you have another idea about why google is going so slow today? Leave a comment below!
