In the week before last I added four more Pi servers to my cluster. My site had served 45,000 pages in the last 30 days, so I decided to add some more horsepower. Here’s a picture of my new cluster with new racks:

Since then the Raspberry Pi Foundation posted a link to my site on their Facebook page and their Google+ page. This caused a huge spike in traffic. I got over 1,000 hits in the first hour:
