台灣Yahoo 的DNS Server似乎有狀況
 

今天是2014年7月22日 , 一早就發現Yahoo無法連線 , 暫時不以為意
結果沒想到,到了快10點多狀況依舊!!

仔細查了查 , 發現是DNS Server 有問題,它一共有5個IP代理回應yahoo.com.tw的查詢
Non-authoritative answer:
yahoo.com.tw nameserver = ns1.yahoo.com.
yahoo.com.tw nameserver = ns2.yahoo.com.
yahoo.com.tw nameserver = ns3.yahoo.com.
yahoo.com.tw nameserver = ns4.yahoo.com.
yahoo.com.tw nameserver = ns5.yahoo.com.

Authoritative answers can be found from:
ns1.yahoo.com internet address = 68.180.131.16
ns2.yahoo.com internet address = 68.142.255.16
ns3.yahoo.com internet address = 203.84.221.53
ns4.yahoo.com internet address = 98.138.11.157
ns5.yahoo.com internet address = 119.160.247.124

從第一個IP開始查起,前兩筆的IP都查不到資料,難怪連不上...
> server 68.180.131.16
Default server: 68.180.131.16
Address: 68.180.131.16#53
> tw.yahoo.com
;; connection timed out; no servers could be reached
> server 68.142.255.16
Default server: 68.142.255.16
Address: 68.142.255.16#53
> tw.yahoo.com
;; connection timed out; no servers could be reached

後三筆才查得到資料,才可以連上!! 透過自己的DNS Server去查會查不到,透過SEEDNET也查不到
但是168.95.1.1居然查得到.... :shock:

這也就是為什麼,沒有人反應yahoo.com.tw的連線有問題 , 感覺真的是積非成是 !!
yahoo.com.tw的網管也是不盡責,居然沒發現DNS Server前兩個IP有問題.... :jolin: :jolin: :jolin:

剛測了一下沒問題啊

怪了,我這邊一點改善都沒有,一直問到ns3 才有回應 ....

我查了一下是否是自己的DNS Server有問題,結果是沒有問題,查了udn.com , www.pcdvd.com.tw 及 www.google.com.tw

都很順利沒有問題!! 看起來似乎還是yahoo.com.tw的DNS Server有點問題....

鵝只知道鵝user的mail server上queue了1xxx封tw yahoo的mail,害鵝以為是不是user的機器出問題了:stupefy::stupefy:....

鵝大,建議那台Server的DNS Server暫時指向168.95.1.1 ,這樣應該可以迅速消化一些mail ....

好玩的是,似乎yahoo.com.tw的網管還沒發覺得樣子.... 真是失敗的監控!! :think:

難怪最近我覺得首頁連Yahoo很慢 :stupefy: ，還以為是自己的IE8或是網路有問題，可連其他地方的網頁又不會變慢，原來是Yahoo的Server出包，請問anderson1127大，這要怎麼自行解決呢 :confused: ? 謝謝 :ase 。

前幾天就開始了...

只有某些時段比較順!!!其餘大部分都很慢!!!

我原本還以為是我自己網路的問題...但是連其他網站都沒事...就知道雅虎那邊應該有點事情!!!

目前的暫時解決方法就是將您自己的DNS IP設為168.95.1.1 (手動設定) , 這台DNS IP算是
Hinet拋不掉的包袱 , 目前hinet也不敢隨意關閉 !! 因為影響層面大 ....

看看有沒有人去向yahoo客服說吧!! 這種事是可以向yahoo客服申訴就是了....

時間是下午的2:15 分 , 總算yahoo.com.tw的所有DNS Server回應都正常了...
很沒效率 , 不過總算是都恢復正常了!! 如果有店家網拍等進行商業交易的廠商,建議可以將我這篇的文章
做一個截取當做證據 , 向yahoo.com.tw請求賠償或者補償 , 相信不無小補!! :agree: :agree: :agree:
