“This seems to have been triggered by a transient anomaly inflicting two reactions within the node, some disconnected from a peer, others threw an exception and restarted,” the submit stated, explaining the sudden disruption.
Regardless of a momentary degradation, the Cardano community recovered with out exterior intervention. As defined within the submit, “such transient points” had been thought of within the node design and consensus and “the methods behaved precisely as anticipated.”
Throughout the anomaly, which occurred between block 8300569 and 8300570, block manufacturing reportedly stored going however was slowed for a couple of minutes and the “affect was low, akin to the delays that happen throughout regular operations.”
“Most nodes robotically recovered, relying on the SPO of alternative.”
On the time of writing, the foundation explanation for the anomaly and ensuing node disconnections and restarts are nonetheless below investigation.
“We’re now investigating the foundation trigger for this anomalous habits and implementing additional logging measures alongside our common monitoring procedures,” acknowledged the official announcement.
Tom Stokes, the co-founder of Node Shark and a Cardano SPO, reported in a Jan. 22 submit that greater than half of the listed nodes had been affected.
He additionally shared a chart displaying the place the community sync fell from 100% to barely above 40% for over 300 reporting nodes.

One other SPO reported related points to Stoke in a Jan. 22 submit, however declared “Some SPOs noticed no affect.”
“Others had relays and BPs restart. SPOs, Devs, and IOG are in Discord debugging atm. No root trigger but,” they stated.
