The Wayback Machine is a 150 billion page web archive with a front end to serve it through the archive.org website.

Today the new machine came to life, so if you using the service, you are using a 20' by 8' by 8' "machine" that sits in Santa Clara, courtesy of Sun Microcomputer. It serves about 500 queries per second from the approximately 4.5 Petabytes (4.5 million gigabytes) of archived web data. We think of the cluster of computers and the Modular Datacenter as a single machine because it acts like one and looks like one. If that is true, then it might be one of the largest current computers.

On another note, we got a nice letter from the last living director of the Rocky and Bullwinkle Show, Gerard Baldwin, because he read about the "fantastic project". Our Wayback Machine is a tribute to their more cleverly named "Waybac Machine" which in turn was a reference to the Univac. Sherman and Peabody live on.
