今天中午突然发现无法访问 https://steemit.com 了.

显示如下:

小睡一会后再试:

在QQ群里讨论，有的说能访问，有的和我一样无法访问
所以我尝试研究看看到底咋啦？

• 在命令ping域名:
  
  ping正常工作, IP地址：167.114.34.68

---

• 在浏览器中直接访问这个IP，效果和访问域名一样.
  
  但是为啥有的朋友能工作呢？

• 用 EzDig工具测试:
  结果如下:

 ; <<>> EzDig 3.0 <<>> @198.153.194.1 steemit.com A

steemit.com 1800    IN  A   167.114.34.89
steemit.com 1800    IN  A   167.114.34.81

;; AUTHORITY SECTION:
steemit.com 3600    IN  NS  ns38.domaincontrol.com
steemit.com 3600    IN  NS  ns37.domaincontrol.com

可以看到A记录有四个IP地址.

• 在浏览器中直接访问IP地址 https://167.114.34.59 居然工作正常!

使用Softlayer机房的一台主机测试.

• 查了一下167.114.34.68 的PTR

 ; <<>> EzDig 3.0 <<>> @208.67.222.222 68.34.114.167.in-addr.arpa PTR
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 24734

;; ANSWER SECTION:
68.34.114.167.in-addr.arpa  86400   IN  PTR node003.steem.house

结论:

Steem.com节点 node003(167.114.34.68) 发生故障了
希望这个问题被及早解决.

补充（1）:
167.114.34.59
167.114.34.89
167.114.34.81
这三个IP都正常

补充（2）:
如果讨厌浏览器的错误提示和小红X
可以编辑hosts文件
