Degraded connectivity in the public overlay
Since September 23, a large number of new nodes that do not forward traffic have appeared in TON’s public overlay. This may degrade external message delivery and block synchronization for participants in the public overlay.
These broken nodes are hosted on the following IP addresses, with multiple nodes per IP:
Major TON services, including exchanges, wallets, Telegram, and Toncenter API, remain unaffected and continue to operate normally, as they do not use the public overlay.
Activation of the new Plumtree broadcasts in the public overlay is scheduled for October. This will improve delivery reliability even when a large number of nodes do not forward traffic.
Exchanges and custodial services experiencing issues should reach out to their technical contact at TON for assistance.
Other developers are advised to use one of the public HTTP APIs alongside their own nodes.

The nominator-pool v1 smart contract is now deprecated.
Operators using nominator-pool v1 should plan their migration based on the number of nominators in their pool:
1. One nominator: migrate to single-nominator v1.1.
2. Multiple nominators: migrate to nominator-pool v2.
Both contracts are supported by MyTonCtrl, the validator management tool.
Both contracts can be used with a vesting contract.

Attention, node operators!
The TON Blockchain has completed its transition to new public overlay broadcasts. Nodes that have been updated to release 2026.10 and have a working QUIC port should experience much more stable network connectivity from now on.
Those that have failed to upgrade will experience a loss of synchronisation; please make sure to apply 2026.10 update as soon as possible.
