While developers are currently investigating, we have identified block finalization delays that are causing blocks to not be confirmed on the primary network.

“Developers across the community are currently investigating block finalization delays that are causing blocks to not be confirmed on the primary network.” The avalanche occurred at 6:30 a.m. ET, the incident report states.

According to data from the Avalanche blockchain explorer, the last block on the Avalanche subnet (P-Chain,

Kevin Sekniqi, co-founder of Avalanche developer Ava Labs, later clarified, as he had previously suggested, that “the issue appears to be a gossip-related mempool management bug. This is purely a code-related bug and not a performance handling issue.” This event seemed to be associated with a new wave of inscriptions. “The inscription appears to have been hit in an extreme case, but it did not affect performance,” he added.

The Avalanche updated the incident report at 11 a.m. ET. “Avalanche validators provide a stake-weighted bandwidth allocation for each peer, and this buggy logic caused each node to have its allocation saturated with useless transaction rumors. This dynamic prevented pull queries issued by the validator from being processed in a timely manner. This led to a delay in settlement (as the survey was not processed).”

To fix the issue, the team asked validators to update their nodes to AvalancheGo v1.11.1. “Once enough stakes are upgraded for this release, the consensus will return to normal,” he said.

At 11:36 a.m. ET, the Avalanche said block finalization on the primary network has resumed and the team is monitoring stability. The team finally confirmed the incident was resolved at 12:43 PM ET, about six hours after the outage began.

Pre-Avalanche Power Outage

Prior to today, there was a brief outage in March 2023 that affected subnet C-chain and X-chain.

An issue with an infrastructure provider delayed Avalanche’s block collection on February 1, but did not impact the performance or stability of the Avalanche network or subnets, the team said at the time.

Layer 1 blockchain competitor Solana also suffered a service outage earlier this month due to a series of events in 2022.
