Cardano is a blockchain developed by IOHK (Input Output Hong Kong) that provides secure and scalable platforms for upcoming applications. The project is backed by a strong global community consisting of researchers, developers, and investors.

On Sunday, January 22, 2023, the Cardano blockchain experienced an anomaly in which about 50 percent of all active relays and block-producing nodes were cut off for a few moments before they automatically restarted. The incident occurred between blocs 8300569 and 8300570 at 09:01 UTC.

According to Rick McCracken, Cardano developer, the blackout caused a temporary delay in transactions and "relegation period". However, the network is not dead, and there is no "restart network required."

Last night during the anomaly in the #Cardano network, the whole network didn't die. There was a short relegation period. Most of the affected nodes have recovered well. No network restart is required," wrote Rick McCracken DIGI (@RichardMcCrackn) in a Twitter tweet on January 22, 2023

However, Cardano developer, Global Output Input (IOG), announced that the issue was only temporary and had been fixed in Cardano's node design and consensus.

The IOG states that the system behaves exactly as expected. Block production was only affected for a moment during the anomaly. Part of the network was not synchronized for a short time before the nodes automatically recovered. The IOG emphasizes that the impact of the incident was trivial and similar to the delay that occurred during normal operations.

According to the IOG, this incident was only a temporary delay and was not worrying. The IOG also stated that it would monitor the situation and provide updates if there were new developments.
