50% of Cardano nodes hit with disconnection bug, Input Output investigates

Input Output (IO) are investigating the origin of an evident bug that disconnected Cardano nodes — triggering a little outage.

50% of the web nodes disconnected, past restarted for chartless reasons connected Jan. 22, IO reported. However, the contented did not impact borderline nodes, which enactment arsenic gateways for extremity users to scope “worker nodes.”

“This impacted relay nodes and artifact producing nodes – borderline nodes look to person been unaffected.”

Cardano node disruption was “a transient anomaly”

IO played down the seriousness of the disruption, stating that the incidental was “a transient anomaly” affecting immoderate nodes. Additionally, the developers said specified eventualities “were considered successful the design,” meaning nary surprises oregon terrible disruption resulted.

“This appears to person been triggered by a transient anomaly causing 1 of 2 reactions successful the node; immoderate disconnected from a peer, others threw an objection and restarted.”

Block accumulation was concisely impacted, temporarily causing the web to autumn retired of sync, but specified instances tin hap during mean operations — specified arsenic erstwhile transitioning betwixt epochs — said IO.

Rick McCracken, pb SPO astatine the Digital Fortress involvement pool, said the anomaly did not sound retired the network. Still, determination was a little model “of degradation,” with the web resuming mean operations aft the affected nodes restarted.

“There was a little play of degradation. Most nodes impacted had gracefully recovered. No web restart was required.“

Input Output to further investigate

Comments posted by SPOs successful a GitHub post pinpointed an contented with relay and shaper nodes, but not each posters experienced that contented — the contented passed wrong 5 minutes without immoderate enactment required connected the portion of SPOs.

Despite the anomaly’s debased impact, IO said it would further analyse the incidental by looking for the basal cause. In the meantime, it volition proceed to way web performance.

“We’re present investigating the basal origin for this anomalous behaviour and implementing further logging measures alongside our regular monitoring procedures.”
