EDGECAST ROUTE: THE WORLD’S FASTEST DNS SERVICE This presentation gives an in-depth explanation about EdgeCast Route, the company’s new globally distributed DNS (Domain Name System) service. DNS is required to ensure that a web site is available to end users, yet it is often neglected, under-prioritized, or deployed on old and insecure infrastructure. This means that many online enterprises are at risk for degraded performance, malicious attacks, or worse – being unreachable via their domain names. After an extensive review of the existing DNS market, EdgeCast sees an opportunity to offer enterprise-grade DNS features and functionality with a simple and cost-effective pricing structure. Customers switching from competitors are likely to realize significant savings while benefiting from vastly superior performance and functionality.

transiting, and knowledge of the topologically
closest EdgeCast PoP to ensure consistently fast
responses regardless of end-user location.
 Leverage the EdgeCast global IP Anycast network
and high performance ROUTE DNS system instead of
building it yourself. Take advantage of EdgeCast’s
global capacity, performance and security

EdgeCast Route
DNS Zone Management
Features
 Allows the creation and management of DNS Zones
o A Zone is the portion of the DNS namespace to which
authority is delegated. It contains records via which
an authoritative name server can provide a response
to DNS queries
o DNS Record Types supported include:
• A (IPv4), AAAA (IPv6), CNAME (Alias), MX (Mail
Exchange), NS (Name Server), PTR (Pointer), SOA (Start
of Authority), SPF (Sender Policy Framework), SRV
(Service Locator), TXT (Text)
 Define load balancing and failover configurations
for address records associated with each zone
o Zone Management User Interface (UI) is integrated
with Load balancing, Failover and Health Check
Management system UIs

 Never leave the zone screen to configure load
balancing, fail-over groups, or health checks
 Up and running in ~5 minutes
 DNS changes typically published to EdgeCast DNS
servers in less than 60 seconds
 Intuitive user interface makes it easy for both the
DNS novice and expert
o Simplifies administration and improves reliability over
common manual edits

EdgeCast Route
DNS Load Balancing
Features Benefits
 Distribution of requests between multiple servers
o Redundancy ensures data availability
 EdgeCast authoritative name servers automatically
pick between servers when resolving a hostname
to an IP address based on pre-defined allocation
 You are not required to be an EC CDN customer or
to have EC manage your zone
 Traffic for a load balanced hostname is
distributed among the servers associated with it
o If a server in a load balancing group is not
available requests to the corresponding hostname
will be balanced among the remaining servers
 Traffic can flow from:
o A Zone managed by EdgeCast
o A CNAME record – including ones created a 3rd-
party DNS provider that owns your zone
o A Subdomain delegation
 Web portal used to create load balancing groups
o Assigned weight given to each server (VIP)
 Configured with/without global health checks

EdgeCast Route
Server (Global) Health Checks
Features Benefits
 Consensus model for health checks ensures against
false positives
 Automated or manual reinstatement of servers
 Check server health status at customer defined
intervals
o Servers polled at customer-defined intervals
• Send HTTP/S GET, HTTP/S POST, or TCP/TCP SSL request
from the EdgeCast Health Check agents
• More frequent polling
o Worldwide distribution of health check agents
• Majority consensus used to determine whether traffic
should be pulled from a server
• Service failures are reported by email within a few
milliseconds once health checks are completed
 Health Check User Interface (UI) is integrated with
Zone Management system UI

primary server cannot fulfill its responsibilities
o Prevents server outage from impacting site traffic
 You are not required to be an EC CDN customer or
to have EC manage your zone
 You can chain the load balancing groups by CNAME.
 Establishes primary and backup relationship
between 2 two targets
o Health check configuration used to determine
when to fail traffic over to backup server
• Assigned to each IP address
o Primary service failure results in DNS traffic being
routed to the backup service
o Supports both IPv4 and IPv6
o Failed services automatically or manually reinstated
 A failover configuration established for traffic from:
o A Zone managed by EdgeCast
o A CNAME record – including ones created a 3rd-party
DNS provider that owns your zone
