The Open Network (TON), a blockchain project linked to Telegram, has resumed operations after experiencing a temporary outage on June 1 that disrupted block production. The issue was swiftly addressed by TON developers, who deployed a fix within 40 minutes of identifying the problem.

What Caused the Outage?

According to an official update from TON, the outage was triggered by an error in the processing of the masterchain dispatch queue, which temporarily halted the production of blocks on the network. The development team quickly isolated the root cause and implemented a corrective patch to resolve the issue. Only a few masterchain validators needed updates to restore network consensus and resume block production.

Impact on Users

Developers assured users that no assets were affected during the disruption. A detailed post-mortem analysis of the incident is expected to be published in the coming days to provide further insights into the event and preventive measures for the future.

Outages Across High-Throughput Blockchains

Outages are not uncommon in high-throughput blockchain networks. Similar incidents have been reported with platforms like Solana and Sui, where node consensus issues or software bugs disrupt operations. These problems are often triggered by sudden spikes in network activity or flaws in code logic.

TON’s History of Service Interruptions

This is not the first time TON has faced disruptions. In August 2024, the network experienced two major outages following overwhelming traffic caused by the launch of the DOGS memecoin. On August 27, block production halted at workchain block 45,341,899, requiring a coordinated node reset by validators to resume operations. Another outage on August 28 lasted approximately six hours, pausing production at block 45,350,522.

Additionally, in December 2023, a surge in TON20 transactions caused a significant drop in transaction speed, with throughput falling from 100,000 transactions per second (TPS) to under one. This issue was traced to validators using underpowered hardware. TON developers quickly issued a patch, encouraged hardware upgrades, and introduced penalties for network participants failing to meet performance standards.

Continued Interest in TON Despite Setbacks

Despite these technical challenges, the TON ecosystem continues to attract significant interest from investors and users. In March 2025, the project secured $400 million in funding from prominent firms, including Sequoia Capital, Draper Associates, CoinFund, and SkyBridge. This funding demonstrates strong confidence in TON’s long-term potential and ability to overcome obstacles.

As blockchain technology evolves, occasional disruptions highlight the importance of robust infrastructure and active development teams. TON’s swift response to outages underscores its commitment to maintaining network reliability and user trust.

Key Takeaways

  • TON’s recent outage was resolved within 40 minutes, with no user assets affected.
  • Outages in high-throughput blockchains are often caused by software bugs or sudden network activity surges.
  • TON has experienced multiple service interruptions in the past but continues to grow and attract investor interest.
  • Recent funding of $400 million highlights strong confidence in TON’s ecosystem.
