Arbitrum suffers ‘partial outage’ amid traffic influx

Developers blamed “a significant surge in traffic” for the problem

A “significant surge in traffic” resulted in a “partial outage” of the Ethereum-based layer-2 network Arbitrum on Friday.

The problem involved Arbitrum’s sequencer. Sequencers are key components of layer-2 networks, serving to process and order transactions in blocks that are then added to the core network — in this case, Ethereum.

The outage has lasted nearly two hours, according to Arbitrum’s status page. “We are working to resolve as quickly as possible and will provide a post-mortem as soon as possible,” the team wrote in a post on X.

Arbitrum’s sequencer suffered a two-hour outage in early June, as Blockworks previously reported. That outage was the result of a software bug, developers said at the time. 

Arbitrum is Ethereum’s largest layer-2 network, encompassing $2.34 billion in total value locked (TVL) and roughly $720 million in transaction volumes over the past day, according to DefiLlama data. 

Layer-2 networks like Arbitrum are designed to offload some transaction volume off the main chain. 

This is a developing story.

Research

Every distributed system inherits the physical limitations, or advantages, of the network it runs on. Physics-bound systems can optimize their execution layers, compress their state, and parallelize their runtime, and still lose time they cannot recover to the speed of light through fiber and the routing decisions of carriers that are not optimized for consensus. The public internet routes traffic by least cost, not best performance. For a system where the order and timing of messages determine who earns and who loses, that is a structural tax and a measurable networking design flaw for traders.
