For almost ten years, Netcraft has measured and made available the response times of leading hosting providers' websites. These performance measurements are made at fifteen minute intervals from separate points around the internet across North America and Europe. Each month, Netcraft publishes the results online. Datapipe is amongst the most reliable sites monitored by Netcraft, with a 100% uptime record over the past 7 years, and 99.99% over 9 years.
