The TON Network Relaunched After A Technical Outage Of 40 Minutes

Hacks, quantum risks… and outages. The crypto universe, in search of maturity, remains shaken by its own vulnerabilities. Network interruptions, too frequent, worry investors. They serve as a reminder that decentralization does not guarantee infallibility. The latest example: TON, the blockchain supported by Telegram, suffered a sudden halt. A technical failure interrupted block production. It lasted nearly 40 minutes on June 1, 2025. Although quickly managed, the incident rekindles the debate on the resilience of high-performance blockchain networks.

The Open Network (TON): Understanding the June 1 Outage

On June 1 at 12:51 UTC, the TON network stopped producing new blocks. An error in the management of the “masterchain dispatch queue” caused it. Very quickly, TON’s technical teams reacted. A quick update of some validators was enough to restore the situation. By 13:30 UTC, the network resumed normal block production.

“A patch was released quickly, and updating a few validators was sufficient,” the team confirmed on X. They added:

The incident was related to an error in processing the masterchain dispatch queue.

No loss of funds was reported. Pending transactions were able to be processed after recovery. This rapid intervention is reassuring, but the recurrence of this type of incident leaves a bitter taste. In a demanding crypto ecosystem, the reliability of an L1 network like The Open Network remains essential. Especially given growing adoption and strong media exposure. Telegram is the public interface of a crypto project that has become indispensable.

The DOGS Crypto and the August 2024 Precedent

This is not the first time TON falters under pressure. In August 2024, the blockchain experienced several outages within less than 48 hours. The cause: the massive enthusiasm around the DOGS memecoin . This token, linked to Telegram’s imagery and the “Resistance Dog,” had exploded traffic on the network.

Peaks of 67,000 transactions per second were recorded. Validators lost consensus, forcing a restart at 4:00 UTC. The bug froze block production for nearly six hours. Several exchanges, including Bybit, suspended TON withdrawals and deposits for safety.

Here are some key figures from this DOGS crisis:

• $1.7 billion in DOGS volume over 10 hours;
• 67,000 transactions per second at peak activity;
• 4 million users claimed their airdrop via Telegram Wallet;
• 1.6 million used their DOGS in the following hours;
• Two major network interruptions between August 27 and 28, 2024.

Despite these disruptions, TON remains a central player in crypto. But every outage erodes confidence a little more.

If TON still stands, the alarm has been raised. The foundation itself has acknowledged an imminent danger: Toncoin is on the brink of major suffocation , it has been assessed. Facing the influx of users, the crypto network could lose footing. Massive congestion becomes a structural threat. The stability of the TON network remains a challenge to watch very closely.
