The 88.io domain is directly served by all country reference DNS servers within the 88.io ecosystem, without needing to query the root DNS servers. This enables the private cyberspaces to access 88.io resources independent of external influences.
Each country entity can also provides alternative mirror domains that backup the 88.io domain (in case the 88.io got banned, attacked, blacklisted etc.) These mirror domains receives need realtime updates from 88.io in order to return the most up-to-date result to relevant DNS queries.
For example, in Australia is mirroring the 88.io domain using the 88-io.com domain. In case something bad happens to 88.io, you can use the domain 88-io.com domain instead.
88-io.com is currently operating in backup mode, designed to be used when 88.io has problems. It will be upgraded to full mirror mode sometime in year 2025, so it can be used concurrently with 88.io. That is, either 88.io or 88-io.com can be used at anytime for any operation.
