纳斯达克卡特雷特数据中心网络中断 全美股票数据馈送出现间歇性缺口
纽约讯——据路透社10月15日报道，纳斯达克（Nasdaq）当天通过系统状态消息通报，其位于新泽西州卡特雷特（Carteret）的数据中心设施发生网络中断，源自该设施的多个组播（multicast）数据通道受到影响，纳斯达克旗下全部美国股票市场的数据馈送出现间歇性缺口。
纳斯达克在通报中提醒客户，其美国股票数据馈送可能出现间歇性数据缺口。故障发生在周四美股交易时段，路透社于美东时间上午11时57分许引述该系统状态消息发出报道。截至发稿，纳斯达克尚未宣布故障排除，也未发布任何交易暂停通知，美股交易继续进行，纳斯达克方面尚未说明故障原因。
数据馈送是交易所向券商、交易机构和行情服务商实时传送报价与成交信息的通道。出现间歇性缺口，意味着依赖卡特雷特设施直连馈送的市场参与者，在故障期间获取的行情信息可能不完整。
卡特雷特数据中心是纳斯达克的核心设施，其股票撮合引擎长期在此运行，大批券商与交易公司也在同一设施内部署服务器，以缩短数据传输延迟。当天美股主要指数走低、科技股领跌，市场同时消化大超预期的9月批发通胀数据（本网今日已报道），故障的后续进展备受市场参与者关注。
Nasdaq Network Disruption at Carteret Data Center Causes Intermittent Gaps in U.S. Equities Data Feeds
NEW YORK — Nasdaq said in a system status message on Thursday that it was experiencing a network disruption at its data center facility in Carteret, New Jersey, affecting multiple multicast groups originating from the facility and causing intermittent data gaps across the data feeds of all of its U.S. equities markets, Reuters reported on October 15.
Nasdaq warned customers that its U.S. equities data feeds could see intermittent gaps. The disruption occurred during Thursday's U.S. trading session; Reuters carried the system status message at about 11:57 a.m. Eastern Time. As of publication, Nasdaq had not announced that the problem was resolved and had issued no trading halt notice; trading continued, and Nasdaq had not given a cause for the disruption.
Data feeds are the channels through which exchanges stream quotes and trade information in real time to brokers, trading firms and market data vendors. Intermittent gaps mean that market participants relying on direct feeds from the Carteret facility may have received incomplete market information while the disruption lasted.
The Carteret facility is Nasdaq's core data center, home to its stock matching engines for many years, and large numbers of brokers and trading firms co-locate servers in the same facility to cut data transmission delays. Major U.S. indexes were lower on the day, led by technology stocks, as investors also digested a much hotter-than-expected September wholesale inflation reading reported earlier Thursday.
