During his scary encounter with the 4- to 5-foot-long (1.2-1.5 m) shark, Smith Point Beach lifeguard Zack Gallo was bit in the chest and right hand, Suffolk County Executive Steve Bellone reportedly stated at a news conference.,"He was playing the role of a victim, and in the midst of that, actually became a victim when this shark bite occurred,” the official noted.,Bellone reportedly claimed that Gallo defeated the shark by "punching down" on it. According to the report, the lifeguard's hand injuries "occurred as he was beating off the shark," and after that interaction ended.",The lifeguard reportedly was "bleeding significantly" when other guards who were already in the water for the exercise raced to aid him, but the victim surprisingly managed to get out of the water unaided.,After being bandaged, the injured lifeguard was brought to a nearby hospital.,“Fortunately, he is doing well,’’ the official said. “He’s in very good spirits at Southside Hospital … getting some stitches.",The attack caused the beach to be closed. Later, the same shark may have been spotted by police using a drone to monitor the ocean, according to the report, but the authorities could not determine if it was the same shark or not.,Even more to the news about sharks getting dangerously close is that Cupsogue, a second beach east of Smith Point, was also reportedly closed on Sunday "due to dangerous marine activity.",On July 1, a 57-year-old swimmer in the area of Jones Beach in Nassau County experienced a "possible shark bite," the police said. This incident prompted the authorities to increase beach patrols ahead of Fourth of July.,Shark attacks on Long Island are "very rare," but recently they have reportedly become more frequent. More shark sightings have occurred in the last two years than in the prior ten years combined.,Two Women Killed in Shark Attack Off Egypt's Red Sea CoastYesterday, 13:00 GMT。

B | 但真实体验下来，这中间的差距，可能就是“网站能打开”和“网站打不开”的区别。    CN2 GIA到底是什么？    CN2 GIA是中国电信推出的高端国际网络线路，全称“ChinaNet Next Carrying Network Global Internet Access”。简单说，它是专门为国际业务优化的“VIP通道”。    实测差距有多大？    普通国际线路在晚高峰时段，国内访问海外服务器的延迟可能飙升至400ms以上、丢包率高达10%-30%。而CN2 GIA线路能将延迟稳定在130-160ms，丢包率控制在2%以内。    美国西海岸普通线路晚高峰延迟约200-300ms，丢包率5%-8%。CN2 GIA优化线路可降至140-150ms，丢包率控制在0.5%以下。差距不是一点点，是数量级的差别。    哪些业务最怕“普通线路”？    并不是所有业务都必需CN2 GIA。但如果属于以下场景，线路差异直接决定成败：    跨境电商独立站：加载速度每慢1秒，转化率可能下降20%    WordPress管理后台：文章保存、图片上传对抖动极度敏感    金融交易/支付回调：丢包可能直接导致订单失败或重复扣款    远程运维SSH：输入延迟、文件同步卡顿，效率大打折扣    普通线路什么时候能用？    如果你的目标用户全部在海外（比如纯面向欧美客户的网站），且国内几乎没人访问，那普通线路完全够用。

C | 但如果你的业务需要国内运营人员频繁登录后台、或者有部分国内客户访问，CN2 GIA的价值在于为每一次请求提供“可预期”的稳定体验，而非某一时刻的极速表现。    选型建议：    面向国内用户 → 必选CN2 GIA    面向海外用户 + 国内运维 → 建议CN2 GIA    纯面向海外 → 普通线路即可，省钱    买之前用测试IP traceroute一下，看看路由里有没有59.43——有就是CN2，没有就是普通线路。
