Cardano (ADA) Network Bounces Back After Node Outage

An anomaly occurred on the Cardano (ADA) blockchain wherein approximately 50% of all active nodes briefly disconnected.

  • An anomaly occurred on the Cardano (ADA) blockchain wherein approximately 50% of all active nodes briefly disconnected.
  • The anomaly caused transaction delays and a momentary degradation, but the network was not required to restart.
  • Input Output Global (IOG) announced that the event was a non-concerning anomaly and that the systems behaved as expected.

On Sunday, January 22nd, 2023, the Cardano blockchain experienced an anomaly in which approximately 50% of all active relay and block-producing nodes disconnected for a short period before they automatically restarted. The incident occurred between block 8300569 and 8300570 at 09:01 UTC.

According to Rick McCracken, a developer for Cardano, the outage caused transaction delays and a momentary “period of degradation.” However, the network did not go down, and no “network restart was required.”


McCracken tweeted:

Despite the incident, Input Output Global (IOG) announced that the event was non-concerning, as such transient issues were considered in the design of the Cardano node and consensus, and the “systems behaved exactly as expected.”

Block production was only momentarily impacted during the anomaly. A portion of the network was unsynced for a short period before nodes automatically recovered. IOG published an SPO announcement emphasizing the triviality of the impact “akin to the delays that occur during normal operations and often seen at epoch boundaries.”

A Transient Anomaly

In the statement, IOG disclosed that the incident “appears to have been triggered by a transient anomaly” that caused one of two reactions in the node; some exceptions restarted, and others disconnected from a peer.


IOG is investigating the root cause of the anomaly and is working to implement additional monitoring and logging measures. By doing so, they aim to prevent similar incidents from transpiring.

The Cardano Community Responds

The chief technology officer of Cardano-based DEX SundaeSwap, Pi Lanningham, tweeted in response:

“The real takeaway for me is how impressively resilient the Cardano network is. Something took down ~60% of nodes, and the network recovered in a few minutes and continued producing blocks throughout.”

The Cardano (ADA) community is anxious to see how the outage will influence the trading price and volume. Still, the price has maintained a stable approximate trading volume of $0.37 USD, an increase of 7.02% over the last week.

On the Flipside

  • A similar event occurred on Solana’s (SOL) Mainnet Beta cluster on May 3rd, 2022. The outage continued for seven hours.
  • The Cardano blockchain has not experienced any outages for five years; the recent incident occurred with minimal downtime.
  • The swift resolution of the outage reflects the practices and anticipation behind the development of the Cardano blockchain.

Why You Should Care

The anomalous incident on the Cardano blockchain has once again highlighted the importance of decentralization and the need for robust nodes in any network.
