Cardano stake pool operators (SPO) and users have been reporting at least half of the nodes for the network briefly went offline over the weekend.
According to a post shared on the Telegram SPO for Input Output Global, the engineering and research in fintech behind the Cardano blockchain, an anomaly caused 50% of Cardano nodes to disconnect and restart.
This appears to have been triggered by a transient anomaly causing two reactions in the node, some disconnected from a peer, others threw an exception and restarted, the post read while explaining the sudden disruption.
Despite a momentary degradation, the Cardano network recovered without external intervention. As explained in the post, such transient issues were considered in the node design and consensus and the systems behaved exactly as expected.
During the anomaly, which happened between block 8300569 and 8300570, block production reportedly kept going but was slowed for a few minutes and the “impact was low, akin to the delays that occur during normal operations.”
