Datacenter Redundancy
We achieve redundancy through load balancing, redundant fiber connectivity, power protection, backup generators, and off-site backups. This approach allows us to proactively and conveniently take a datacenter off our global network whenever such a catastrophic event or maintenance occurs. It also allows us to do maintenance on our network more easily than other DNS resolvers.
Fail Open
When technology fails closed, it completely shuts down when it fails. Since we’re dealing with network traffic impacting thousands of customers and billions of DNS queries, we don’t have the luxury of failing closed—and neither do you. That’s why we’ve engineered DNSFilter to fail open. This means that no matter what happens across our architecture, even if one element fails, we continue operating. Backups take over until the issue is resolved and we can get our normal architecture back online.
