Global DNS Failover Solution
Global DNS Failover using IP Anycast & BGP
- Data centers on both coasts, San Jose California, Sterling Virginia announce the /23
aggregate.
- Both Data centers announce one /24 out of the larger /23 supernet. For example, San
Jose will announce the upper /24 and Sterling will announce the lower /24. If San Jose fails to respond,
DNS queries destined for San Jose will be routed to Sterling because Sterling will contain the next
longest network match, the /23, and be fulfille by the name servers there.
- Our Global DNS Failover offeres many advantages including:
- Fewer DNS queries failures.
- Scalable to handle multiple name servers in multiple locations.
- Improved performance and load-handling.
- The Nominum network naming solution provides
many advantages including:
- 6 completely redundant nameserver solutions.
- Anycast technology, which increases DNS resolution time by directing requests to the nameserver which is
the closest to the requestor.
- Centralized DNS distribution, which allows your DNS changes to be simultaneously broadcast to all
nameservers. This allows for solid redundancy, should one of the nameservers stop responding.
- Hot fail over for all nameservers, which provides an uninterrupted flow of DNS resolution, even if one
or more of the nameservers should fail to respond.
