CNN辟谣：波士顿马拉松爆炸案的五大谣言

Reports flew around social media, mainly Twitter, on Monday that police in Boston had shut down cellular networks to prevent an attacker from using a cell phone to detonate another explosive. At least one media report quoted an unnamed source with information to that effect, before later recanting.
网上还流传这样的消息：15日当天波士顿警方关闭了移动网络以防止袭击者用手机来引爆另一个爆炸物。至少有一个媒体使用“匿名消息人士”说法报道这个信息，但媒体随后又撤回报道。

In truth, Boston's wireless network was simply overwhelmed with the volume of calls and other communications in the aftermath of the attack. Service was slow and spotty, but never shut down. Verizon and other mobile carriers confirmed they'd never been contacted by officials asking them to shut off service.
真相是：波士顿无线网络只是由于袭击事件发生后巨大的通话量和其它通讯而承受了非常大的压力，服务很慢而且时有时无，但从未关闭过。Verizon和其它手机运营商证实，政府官员们从未就关闭服务联络过他们。

Soon after the bombings, mobile carriers were beefing up their networks in the Boston area. AT&T made its Wi-Fi system publicly available for free to help take the load off traditional phone lines.
在爆炸发生后不久，移动运营商在波士顿地区加强了他们的网络。AT&T免费开通了它的Wi-Fi系统，以帮助缓解传统电话线的流量。
