摘要：An infrastructure “insurance” mechanism enables a Web site to fail over to acontent delivery network (CDN) upon a given occurrence at the site. Upon such

occurrence, at least some portion of the site's content is served preferentially from theCDN so that end users that desire the content can still get it, even if the content is not

then available from the origin site. In operation, content requests are serviced from thesite in the usual manner, e.g., by resolving DNS queries to the site's IP address, untildetection of the given occurrence. Thereafter, DNS queries are managed by a CDNdynamic DNS-based request routing mechanism so that such queries are resolved tooptimal CDN edge servers. After the event that caused the occurrence has passed,control of the site's DNS may be returned from the CDN back to the origin server's DNSmechanism.
