我的Facebook連線問題和臨時解決辦法

從幾天前開始,上facebook總是斷斷續續到有反應。今晚終於忍受不住而又有半點空閒時間,便試試找找問題。

我使用的ISP是香港寬頻。

試了另一間ISP和Google的DNS來找尋facebook.com的IP地址,也是回傳以下結果。

facebook.com has address 66.220.158.11
facebook.com has address 69.171.224.37
facebook.com has address 69.171.229.11
facebook.com has address 69.171.242.11
facebook.com has address 66.220.149.11
facebook.com has IPv6 address 2a03:2880:2110:3f01:face:b00c::
facebook.com has IPv6 address 2a03:2880:10:1f02:face:b00c:0:25
facebook.com has IPv6 address 2a03:2880:10:8f01:face:b00c:0:25
facebook.com mail is handled by 10 smtpin.mx.facebook.com.

然後試過以上5個IPv4地址的port 80,竟然只有69.171.224.37的web server有反應,以下是telnet的測試方法。而其他4個只能connect,但發任何訊息也沒有反應。

$ telnet 69.171.224.37 80
Trying 69.171.224.37…

作為Linux桌面用戶,在/etc/hosts臨時加上以下一行,暫時解決問題,上facebook也變回暢順。

69.171.224.37 facebook.com www.facebook.com

真正問題的原因有代查明了。
