I am maintaining a website that contains mostly simple html (just a little php). Normally the site receives only 4000 hits per month, but it was recently slashdotted by the New York Times (>30,000 visitors and 30 GB in a day) and the web host provider (bluehost) throttled the CPU in response. This slowed down the website considerably. What web host providers would offer a more scalable solution? Ideally I would like a high-quality host that charges by the GB and can handle bandwidth to expand during sudden slashdotting episodes without a reduction in performance.
