Sui Network Resumes Normal Operations After Six-Hour Outage

Sui Network has resumed normal operations after experiencing a six-hour network outage that halted transactions across the platform according to reports. The Sui Foundation confirmed the issue was resolved on January 13, 2026, after the network stalled at 2:52 pm UTC and was brought back online at 8:44 pm UTC as reported. The outage affected over $1 billion in value and prevented users from transacting on the chain during the period according to data.

The Sui Foundation did not immediately explain the cause of the outage, but confirmed that core developers were actively working on a solution according to the foundation. The network, known for high-speed transactions, has faced previous issues, including a major outage in November 2024 as documented. The current incident has raised concerns about the reliability of Layer-1 networks in the blockchain space according to analysts.

Users reported delays and unavailability of dApps such as Slush and SuiScan during the outage as users experienced. The Sui core team advised users to refresh their apps or browser windows once the network was back online according to guidance. Transactions had completely stopped, and block production was halted, leading to frozen interfaces and failed requests as detailed.

Why Did This Happen?

The exact cause of the Sui mainnet stall was not disclosed by the core team according to reports. However, past incidents suggest that issues with validator coordination or consensus mechanisms may play a role as analysis indicates. The Sui Network, which was launched in May 2023, is known for its parallel transaction processing system, which enables high throughput but can also lead to coordination challenges according to technical reports.

The Sui Foundation confirmed the issue and is investigating the root cause, but no timeline for a full explanation has been provided according to statements. The team has emphasized that they are actively working on a solution and will share updates as they become available as reported.

How Did Markets Respond?

The SUI token initially saw a brief 4% price spike in response to the outage news, but it quickly settled back to around $1.84 according to trading data. Despite the disruption, the token has shown limited market reaction overall, with a 1.22% increase in the last 24 hours as tracked. Trading activity also saw a rise of 75% on the day, with $1.32 billion in trading volume recorded according to volume reports.

Decentralized applications and wallet services on the Sui network were affected, with some dApps reporting slow performance or temporary outages as observed. Users were advised to avoid critical transactions during the stall to prevent potential issues as recommended.

The Sui Foundation has not yet provided an official statement detailing the impact of the outage on users or the broader blockchain ecosystem according to the foundation. The focus remains on resolving the issue and ensuring the network's stability going forward as confirmed.

What Are Analysts Watching Next?

Blockchain observers are closely monitoring whether Sui will roll out emergency updates or patches similar to Solana's recent response to network issues as speculated. Solana has not had any outages in the past 18 months, partly due to its proactive approach in coordinating validator updates according to reports.

Analysts are also watching for further statements from the Sui core team on the cause of the outage and how it will be prevented in the future as noted. The Sui Network's ability to handle high-traffic scenarios will be a key factor in determining its long-term viability as a high-speed Layer-1 blockchain according to analysis.

The SUI token's performance remains under scrutiny as well, with technical indicators showing mixed signals according to technical analysis. While the RSI is in neutral territory and stochastics suggest a buy signal, the MACD is trending in the sell direction as technical data shows. Investors are advised to monitor these metrics closely as the market digests the recent outage and its implications for the network's reliability according to market commentary.

The Sui Network outage underscores the importance of robust infrastructure in the blockchain space as analysts point out. For now, the focus is on ensuring the network remains stable and secure as the team works to address the underlying issues according to the foundation.
