摘要： An infrastructure “insurance” mechanism enables a Web site to fail over to a content 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 the CDN 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 the site in the usual manner, e.g., by resolving DNS queries to the site's IP address, until detection of the given occurrence. Thereafter, DNS queries are managed by a CDN dynamic DNS-based request routing mechanism so that such queries are resolved to optimal 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 DNS mechanism.

摘要： The present invention addresses the known vulnerabilities of Web site infrastructure by making an origin server substantially inaccessible via Internet Protocol traffic. In particular, according to a preferred embodiment, the origin server is “shielded” from the publicly-routable IP address space. Preferably, only given machines (acting as clients) can access the origin server, and then only under restricted, secure circumstances. In a preferred embodiment, these clients are the servers located in a “parent” region of a content delivery network (CDN) tiered distribution hierarchy. The invention implements an origin server shield that protects a site against security breaches and the high cost of Web site downtime by ensuring that the only traffic sent to an enterprise's origin infrastructure preferably originates from CDN servers. The inventive “shielding” technique protects a site's Web servers (as well as backend infrastructure, such as application servers, databases, and mail servers) from unauthorized intrusion—improving site uptime and in the process, customer loyalty.
