Global server network
DNS servers are critical parts of internet infrastructure. When you rely on Zerigo for your DNS services, you're trusting us to provide those services without interruption.
To that end, we've built a global server network, with DNS servers geographically distributed across North America, Europe and Asia.
Our global network has been carefully built to maximize uptime and reliability. Each production server is fully independent of the others to avoid the possibility of a cascading failure.
We run our servers substantially below maximum capacity to leave plenty of room for traffic spikes or other unanticipated traffic.
Who wants to wait hours for DNS changes to make it to their DNS servers? We don't and we're sure you don't either.
Updates made via our web interface or our API are processed by our custom synchronization engine and reflected in our DNS servers in an average of 30 seconds.
Our super fast DNS updates also make our service great for dynamic DNS.
Ensure your DNS service is prepared for the future with IPv6.
Our nameserver network features native IPv6 connectivity—no tunnels or other sub-standard silliness. Whether your queries come in via IPv4 or IPv6, we're ready to answer all of them.
Of course, we also provide full support for IPv6 address (AAAA) records as well as IPv6 reverse DNS domains.
Our Dynamic DNS service can do IPv6 too—just specify an IPv6 address and we'll automatically look for an AAAA record to update.
Our global DNS network has been carefully engineered to be reliable and fault tolerant. Every DNS server is fully independent so there's no possibility of cascading failures.
Our promise of a reliable network is backed up by our DNS SLA which guarantees overall network uptime of 100% and individual server responsiveness at 99.99% (see the SLA for details).
If you have DNS information that may need to change on short notice, fast updates are only half of the equation. The other half is support for low TTL (time-to-live, refresh period) values.
Zerigo allows you to fully configure the TTL for each domain and each host record. TTLs can be as low as 1 minute.
