七牛CDN对AWS中国区的EC2 IP地址段地理位置误判

Question

Hi,

如下的地址段54.223.0.0/17。
http://bgp.he.net/ip/54.223.1.1

Announced By

在中国区AWS EC2上，返回了美国的IP地址，导致上传下载都很慢。
$ curl ifconfig.me

好的，了解，通过http://tool.17mon.cn/ip.php 也可以看到，IP段54.222.0.0 - 54.223.255.255是亚马逊中国区的IP，已经通知相关同事进行处理，争取今天可以将地理位置信息库更新完成。

用whois 54.223.136.35 查询到的结果已经在北京。
