[Domain Name System](https://en.wikipedia.org/wiki/Domain_Name_System) (DNS) is a fundamental function of the internet that needs to be accurate and available at all times. ## DNS Redundancy Currently [88.io](http://88.io) provides global DNS services from 8 sites in multiple cities: Amsterdam - 1 site (unicast) London - 1 site (anycast) Los Angeles - 1 site (anycast) Singapore - 1 site (unicast) Sydney - 3 sites (1 unicast, 2 anycast) Tokyo - 1 site (anycast) ## DNS Backup In case there are problems with the real top level domain servers (yes, even those backbone services can go down e.g [due to dnssec problems](https://ianix.com/pub/dnssec-outages.html)), the service will ignore caching time out and keep serving the last records until the proper servers come back up. ## DNS Monitoring These servers perform independent monitoring and verification of global DNS records. ## DNS Privacy These servers to keep logs from a minimum of 5 minutes to maximum of 2 days to prevent attack only. Most records will be deleted with 10 minutes, suspicious records will be kept longer up to a maximum of 2 days. To prevent these servers from collecting you real IP address, you should use your Private Cyberspace to randomise the IP addresses of all your DNS request. ---

The contacttrace.com.au domain's DNS records are now available from 8 sites worldwide. If something bad happens to the .com.au top level domain, people can still access contacttrace.com.au by using these global DNS Servers directly for their DNS lookups. ---

# Personal DNS Server Although [88.io](http://88.io) provides global DNS servers, your private cyberspace has a built in Personal DNS Server you can and should use. Besides stopping ours like [88.io](http://88.io) see you DNS queries, a Personal DNS Server also gives you incredible insight into your own online activity. You can set the DNS server of your devices to use your Personal DNS Server (which varies depending on the brand and model your devices). ---

# Public DNS Resources Instead of using the [Root DNS Servers](https://www.iana.org/domains/root/servers) directly, there are many public DNS servers that performs some form of filtering for your Personal DNS Server. There is a good list of these public DNS servers here: > **[Known DNS Providers | AdGuard DNS Knowledge Base](https://adguard-dns.io/kb/general/dns-providers/)** > > Here we suggest a list of trusted DNS providers. To use them, first install AdGuard Ad Blocker or AdGuard VPN on your device. Then, on the same device, click the link to a provider in this article Your Application Integrator would have selected at least 2 sets of Filtering DNS Servers for your Personal DNS Server, but you can pick whatever DNS Servers you like for use in different situation (e.g. when a child is using your devices). The recommendation is to follow Private Cyberspace usage guidelines and have at least 2 different browsers with different Personal DNS Server settings (e.g. public and private). ---
