支付宝说对不起:以后会尽力让用户无感知

支付宝官方昨日发布声明,对支付宝因光纤被挖断而断网事件道歉。支付宝方面称,因杭州市政道路建设导致网络光缆被挖断,从而使部分用户今日下午短时间出现了无法正常使用支付宝的情况,对此深表歉意。也非常感谢大家的理解!给大家添麻烦了。
同时,支付宝方面也表示,光缆被挖断可能并不能完全杜绝,但对于支付宝而言,会继续推进技术的升级改造,继续完善异地多活的系统架构。未来,即使再次出现光缆被挖断等意外情况,进行异地切换时,也尽量做到让用户最小感知甚至无感知。
以下是支付宝声明全文:
因杭州市政道路建设导致网络光缆被挖断,从而使部分用户今日下午短时间出现了无法正常使用支付宝的情况,对此我们深表歉意。也非常感谢大家对我们的理解!给大家添麻烦了,大家可能关心的问题,我们在此回复如下:
Q:5月27日傍晚,支付宝为什么出现故障?
A:5月27日傍晚,因市政施工导致杭州市某地光缆被挖断,导致了支付宝一个主要机房被影响,随后全国部分用户无法使用支付宝。事情发生后第一时间,支付宝工程师紧急将用户请求切换至国内其他机房。到晚上19时左右,支付宝服务恢复正常。
Q:这次故障影响了多少用户?
A:在故障时间段内使用支付宝的用户具体数量无法精确统计,但可以肯定的是,流量通过其他机房的用户是不受影响的。
Q:为什么杭州的机房光缆中断影响到全国其他地区部分用户?
A:因为这次受影响的是支付宝部署在杭州的一个主要机房,服务的并不只是杭州地区的用户,因此网络中断导致该机房服务器无法为受影响的用户提供服务,这些用户也会包括其他地区。
Q:故障会不会影响到用户的资金安全?
A:支付宝有完善的技术和措施保护用户的资金安全,用户的资金安全不会受到任何影响。支付宝中的任何一个交易,同时都会有多份记录,数据可靠性极高。如果有用户出现交易不同步的情况,后续都会得到妥善解决。
Q:为什么要这么久才恢复?
A:事实上,在当晚支付宝服务恢复时,被挖断的光缆还没有修复。支付宝的异地多活的系统架构在此次意外中发挥了巨大作用。一方面,没有因光缆被挖断而影响全部用户;另一方面,紧急将故障机房的流量切换至了其他机房。我们作为一个金融系统,对切换中数据与资金安全性的要求极高,因此切换速度上没有做到更快。后面我们会不断提升切换速度。但是,这并不代表我们对这次恢复时间是满意的,我们希望未来这样的切换能让用户无感知或者最小化感知。
Q:恢复使用之后,有些用户发现余额宝信息显示不全,支付宝头像也没有了。这是为什么?
A:支付宝将流量切换至其他机房,数据的核对需要一定时间。相关的功能显示,会有一点延时,但数据并不会丢失,这一点,请大家放一万个心。
Q:有什么预防机制,防止类似的情况发生?
A:光缆被挖断可能并不能完全杜绝,但对于支付宝而言,会继续推进技术的升级改造,继续完善异地多活的系统架构。未来,即使再次出现光缆被挖断等意外情况,我们进行异地切换时,也尽量做到让用户最小感知甚至无感知。
