Please prepare for an increased network load and ensure that your validator nodes:
1)
Have added a public collator list in accordance with the previously posted instructions.
2)
Have a working QUIC port.
Currently, validators with the following ADNL addresses do not have an operating QUIC port:
If you find your machine on the list, please urgently check your configuration using the instructions.
3)
Have a system configuration that corresponds to the latest requirements.
Please note that failure to observe the above rules will endanger network stability. If these requirements are not met, we will be forced to submit manual requests to slash specific validators.

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.
