Google Analytics helps you measure how visitors arrive to your site. For example, by traffic source, geography, landing pages, and other dimensions.
Google today announced that they will no longer able to offer data on one of these dimensions: Connection Speed, and are now in the process of deprecating the Connection Speed dimension.
"You will still be able to access historical connection speed data prior to February 25th, 2011 through the current version of Google Analytics and the Google Analytics API. The Connection Speed report in the current version of Analytics will be removed next week. However, you can continue to use Connection Speed as a dimension in custom reports.
For the Google Analytics API, we plan to remove this dimension in three months. Again, this is only for historical data before February 25th, 2011," stated Google.
"If you rely on Connection Speed to understand the effect of page load time and latency, we are working on a solution for you that we expect to have ready in the coming weeks."
