Clicking on a DOI link (try this one: http://c5k9u2.wcbzw.com/10.1109/5.771073) takes you to one or more current URLs or other services related to a single resource. If the URLs or services change over time, e.g., the resource moves, this same DOI will continue to resolve to the correct resources or services at their new locations.
Check the current status of the DOI system at doi.statuspage.io.
