**Claim.** Chainlink's white-list response to the 2020 gas fee attack was only a temporary fix: had the attack impacted 50 percent of Chainlink node operators, the price feed would not have updated until enough nodes returned.

**Type.** failure  **Support.** evidenced

**Holds when.**

- 2020 attack on Chainlink nodes
- oracle networks with limited node counts

**Source quote.**

> Temporary solution known as "white-list", but if the attack had impacted 50% of Chainlink node operators, that feed wouldn't have updated until enough came back up and nodes would not be able to feed information.
