Cardano Network Recovers After Brief Outage Triggered by ‘Transient Anomaly’

The Cardano network suffered a brief outrage on Sunday between blocks 8300569 and 8300570. Stake pool operator Rick McCracken shed more light on the matter and assured the community that the entire network did not go down. He said that an “anomaly” caused nearly 50% of nodes to disconnect and restart.

According to McCracken’s latest tweet, the Cardano network saw a period of degradation, but almost all the impacted nodes had “gracefully” recovered.

• The response comes after several devs flagged an error on GitHub. This affected block production, which slowed down for a few minutes. All nodes, however, restarted automatically.
• The Telegram SPO for Input Output Global (IOG), the engineering and research team behind the Cardano blockchain, explained,

“This appears to have been triggered by a transient anomaly causing one of the two reactions in the node; some disconnected from a peer, and others threw an exception and restarted. Such transient issues (even if they were to affect all nodes) were considered in the design of the Cardano node and consensus. The systems behaved exactly as expected.”

• IOG further said the impact was low and only affected relay and block-producing nodes. Edge nodes, on the other hand, appeared to function normally.
• Solana suffered multiple cases of outages last year, with the worst one lasting up to 48 hours.
• The outages were concerning enough for a protocol that also witnessed overloads and was the most impacted due to its significant exposure to Sam Bankman-Fried’s bankrupt FTX exchange.
• In retrospect, the Cardano community lauded the quick revival of the network without external intervention and the fact that no network restart was required in this case.
