Dear RSSAC Caucus, The RSS Metrics work party has been of two minds somewhat with the purpose of the proposed metrics. On one hand we want metrics that can be used to measure service levels. On the other, we want measurements that could be used to characterize end user experiences and for research into resolver behavior. The purpose of the metrics affects decisions, such as the location and operation of measurement vantage points. In order to make progress, the work party chairs and shepherds recommend that we limit the scope to metrics designed to measure service levels. If we can achieve consensus on this point, then the work party can advance to discussions and decisions about vantage point locations. Resolver behavior and other uses of metrics can be addressed in future revisions of this work or another work party if so desired. If there is any opposition to this proposal, please share your thoughts either on the list, or at the upcoming work party meeting on July 22 so we can discuss, reach consensus and ultimately make progress.
