In the Cardano network, there was a transient anomaly that caused a disconnection and automatic restart of about 50% of the nodes in the network. The incident occurred between blocks 8300569 and 8300570. Both relay nodes and block producer nodes were affected. Some nodes disconnected from peers. Others automatically restarted after throwing an exception. The Cardano client and the network consensus are designed to deal with this kind of event. Most of the affected nodes automatically recovered and resumed their work. The network behaved exactly as expected. The impact of the incident on block production was minimal and short. The cause of the problem is unknown at the time of writing. There is speculation that a block appeared in the network that caused the nodes a problem after receiving it.
- There is probably a bug in the Cardano node that needs to be fixed.
- The network automatically recovered itself without the coordinated efforts of the pool operators.
- The incident did not affect network security.
- We need more Cardano node implementations.
