By CCN: Stellar, the Ripple fork founded by Jed McCaleb after disagreements with decisions at Ripple, went down for about two hours yesterday. Tim Swanson alerted Twitter to the issue, and a Stellar representative confirmed its occurrence.
Experts Notice, Story Goes Viral, Stellar Goes On Defense
Breaking: yesterday the Stellar network went down for about 2 hours… only those who run validators noticed it.
no new transactions were added for ~2 hours.

The incident raises questions about the level of decentralization in Stellar, which uses the same “validator” network design as Ripple. In this design, a few servers validate the transactions of the network at large, and if these servers experience problems, the system can quickly become unusable.
Stellar Improving Decentralization
Stellar’s chief scientist confirmed last month that decentralization is a concern for Stellar. His blog post from April is a response to a separate report by researchers who conclude that Stellar is too centralized to be considered “secure.” The researchers wrote:
“As can be seen from many articles and papers, some network attacks, such as DDoS, can occur in the blockchain networks. In this paper, we are saying that if two centralized nodes can not receive or send any message because of DDoS, then all nodes in Stellar network wull [sic] be blocked and can not move to the next step in the consensus process.”
Jed McCaleb says that Stellar Development Foundation nodes aren’t purely to blame for the outage and that the project has been working on getting people to rely less on these nodes.
