The limitations of BGP routing in the Internet are often blamed
for poor end­to­end performance and prolonged connectivity in­
terruptions. Recent work advocates using overlays to effectively
bypass BGP's path selection in order to improve performance and
fault tolerance. In this paper, we explore the possibility that intel­
ligent control of BGP routes, coupled with ISP multihoming, can
provide competitive end­to­end performance and reliability. Using
extensive measurements of paths between nodes in a large content
distribution network, we compare the relative benefits of overlay
routing and multihoming route control in terms of round­trip la­
