SDF validator nodes went offline around 1 am PDT, halting transaction validation. However, the Stellar network remained operational because other organizations' nodes continued functioning, demonstrating the network's decentralization.

The Stellar Development Foundation's validator nodes stopped working around 1 am PDT, and its public Horizon API instance went temporarily offline. Despite this, the Stellar network continued processing transactions because validator nodes operated by other organizations like COINQVEST, Wirex, and SatoshiPay remained active. The outage reduced the network to 21 validator nodes, with some failing due to reliance on SDF's Horizon API. Exchanges including Bitstamp paused XLM withdrawals while investigating, though Coinbase and others monitored the situation. SDF confirmed the network itself had not halted and remained operational for users running their own Horizon instances.
