We try our best to ensure that the data we publish are accurate and complete before, during, and after they are published. This page lists all of the corrections that we have made.
We may make changes that are not corrections. For example, our Traffic graphs do not show graphs of Google's actual traffic numbers. Rather, the graphs display interruptions in service that are specific to a geographic region. If changing how we generate the data will better serve that goal, we'll make the revision and add a note here to explain it.
By maintaining this change log, we hope to strike a balance between keeping a good historical record, and allowing ourselves to make improvements.
