Avalanche suffers downtime of nearly five hours

An apparent logic error enabled the sending of excessive information, which led to a block production halt.

Avalanche stopped producing blocks at around 11 am (UTC) this Friday and it took over four hours to restore the network. User Kaleo pointed out on X (formerly Twitter) that the network outage time aligned with the launch of a large inscription mint, which might have caused the downtime. Avalanche’s native crypto, AVAX, has suffered a 4% loss since the network outage up to the time of writing.

Patrick O’Grady, VP of Platform Engineering at Ava Labs, urged validators on X to upgrade their nodes to AvalancheGo v1.11.1, stating that this new version “disables logic added in v1.10.18 that lead to validators sending an excessive amount of gossip to each other.”

“Avalanche Validators provision a stake-weighted bandwidth allocation for each peer and this buggy logic led to each node saturating their allocation with useless transaction gossip. This dynamic prevented pull queries issued by the validator from being processed in a timely manner and led to consensus stalling (as no polls were being handled),” explained O’Grady in the same post.

As reported by Crypto Briefing, Avalanche experienced problems in December 2023, when spam of inscriptions resulted in higher network fees and delayed confirmation times for transactions. However, Avalanche didn’t register any outages during this inscription frenzy.
