- Charles Hoskinson, founder of IOG, addressed a two-minute node outage on the network on January 22, 2023.
- Hoskinson discussed the balance between prevention and recovery in distributed systems to contextualize the anomalous event.
- The root cause of the outage is still under investigation. Input Output Global (IOG) stated that the anomaly was not a concern and block production was only affected for a short time.
On Tuesday, January 23, 2023, Charles Hoskinson, founder of IOG and Cardano, tweeted a video in which he hosted a ‘whiteboard session’ to address a two-minute node outage that occurred at Cardano on January 22.

Prevention versus recovery in distributed systems [Whiteboard] https://t.co/BbrApJdhfL
— Charles Hoskinson (@IOHK_Charles) January 23, 2023
In the wake of a node outage that occurred on the Cardano blockchain on January 22, which saw 60% of the nodes go out for a brief period, Hoskinson opined that it was “a little bit, although it wasn’t a flashback,” and reassured the Cardano community that “honestly, it didn’t This was not a big problem” and “it had no effect whatsoever.”
The balance of prevention and recovery
In the 23-minute video, Hoskinson delves into the balance between prevention and recovery in distributed systems, saying:
“The more complexity you introduce, the greater the likelihood that, at any given time, the system will have some bad cells, and the system has to purge those bad cells, especially as it scales.”
Hoskinson highlights that in any “good distributed system” there must be a balance between prevention and recovery and asserts that the Cardano ecosystem experiences “growing pain that is very natural in the design of distributed systems.” He further states that “the fact that we [Cardano] I was able to recover in less than two minutes, which is a good indication that there is a good balance of these features within the system between prevention and recovery given the ‘demons’ we’re up against.”
According to the network’s founder, Cardano could have taken additional precautions to narrow or prevent the potential for problems. He explained how these preventive measures could have included the following “trade-offs”:
These efforts, Hoskinson mentioned, mean the network will have a greater degree of centralization — unlike what Cardano has evolved into.
Cardano node outage – transient anomaly
The short outage of Cardano nodes occurred on January 22, 2023, during which approximately 50% of all active relay and block production nodes were disconnected for a short period before restarting without intervention.
Input Output Global (IOG) claimed that the anomaly was not a concern because block production was only affected briefly, and the network was not temporarily synchronized before most nodes recovered automatically. The root cause of the outage is still being researched.
The Cardano blockchain has not experienced an outage in five years and automatically restored affected nodes with minimal downtime. The rapid recovery after the node outage reflects the detailed methodology behind the development of the Cardano blockchain.
on the flip side
- Hoskinson stated that Cardano has factors to consider regarding the fail-and-recovery model.
- Since the node outage on January 22nd, Cardano (ADA) price has not seen any drastic changes, from trading as high as $0.38 on the day of the outage to a price of $0.35 at the time of writing.
Why should you bother
Cardano node outages, albeit brief and without major network impacts, indicate the distributed system’s “normal growing pains,” according to Hoskinson. These issues are inevitable as transaction volume increases and computational complexity increases.
Flexibility in prevention and recovery protocols is crucial to ensuring the safety of funds on the network.
