The XRP Ledger stopped processing transactions for about 15 minutes earlier today, according to developer Wietse Wind.

Every server in the protocol relies on its own unique node list (UNL) for validating new ledgers.

The quorum requirement is set at 80%. If more than 20% of validators cannot reach consensus or remain unavailable, the network is not able to confirm new transactions.

As explained by Wind, four validators were down, which caused the quorum to drop below the required threshold.

The average close time of a new ledger is about four seconds, but validators were not capable of reaching an agreement, which stopped transaction processing.

The XRP Ledger Foundation claims that the accident did not result in a loss of any transactions.

Wind says that the network is now working properly after a sudden halt:

Finally: your XRP is safe. No history is lost, the XRPL is working. I believe we need more proactive infrastructure operators.

Ripple CTO David Schwarz supported implementing the Negative UNL feature, which ensures that the network can continue making forward progress even when several validators are down. In this way, transactions would continue being confirmed during a temporary outage:

We need to get the negative UNL feature deployed. More validators is also good, but has some of its own tradeoffs.
