Telegram-linked The Open Network has resumed operations after a brief outage on June 1 that halted block production. On June 1, TON developers announced that a fix was deployed 40 minutes after the issue was identified. According to TON’s official update, the incident stemmed from an error in the processing of the masterchain dispatch queue, temporarily disrupting block production. The development team successfully isolated the problem and quickly implemented a corrective patch, as updating only a few masterchain validators was sufficient to resume block production and restore network consensus. Developers have also confirmed that no user assets were affected by the disruption, and a post-mortem of the incident will be published in the coming days. Outages like these are not limited to just TON and have also affected other high-throughput blockchains such as Solana and Sui , among others, over the past year. These outages typically occur when validator nodes lose consensus or encounter software bugs, often triggered by sudden surges in network activity or flawed code logic. For TON, this is not the first time it has experienced service interruptions. In August 2024, the network faced two major outages due to overwhelming traffic from the launch of the DOGS memecoin.

A second outage followed on August 28, lasting around six hours, with block 45,350,522 marking the pause. Another incident occurred in December 2023, when a surge in TON20 transactions led to a drastic drop in transaction speed. TPS fell from 100,000 to under one due to validators operating on underpowered hardware. TON developers issued a patch and encouraged hardware upgrades while promising penalties for network participants who failed to meet performance standards. Despite these technical setbacks, interest in the TON ecosystem has remained strong. In March 2025, the project secured $400 million in funding from major firms, including Sequoia Capital, Draper Associates, CoinFund, and SkyBridge.
