2ch特化型サーバ・ロケーション構築作戦 Part19

Hello Sean-san,
Cc: 2ch guys,

Since about several hours ago, outgoing network performance of tiger505
has been bad (it is reported by many 2ch users).

I checked the network performance of tiger505, and I verified it is
certainly occurred.

I did the performance test by using ftp, and I detected outgoing
network performance has been bad, as follows:

- other servers => tiger505 is good. (it is about 100Mbps)
- tiger505 => other servers is bad. (it is about 50Mbps)

I verified the network setting of tiger505 is still set to 100Mbps
full-duplex (Of course, I don't change the network setting on tiger505).
And I feel the suspicious network delay when I am working on tiger505
via remote login

I checked the network performance by ping from other servers at PIE, and I
detected suspicious delays are occured the response packet as follows:

64 bytes from 206.223.150.120: icmp_seq=104 ttl=63 time=1.105 ms
64 bytes from 206.223.150.120: icmp_seq=105 ttl=63 time=0.569 ms
64 bytes from 206.223.150.120: icmp_seq=106 ttl=63 time=0.642 ms
64 bytes from 206.223.150.120: icmp_seq=107 ttl=63 time=0.567 ms
64 bytes from 206.223.150.120: icmp_seq=108 ttl=63 time=31.387 ms <=
64 bytes from 206.223.150.120: icmp_seq=109 ttl=63 time=0.719 ms
64 bytes from 206.223.150.120: icmp_seq=110 ttl=63 time=0.616 ms

Probably, it is the cause of the trouble I think.
Please check and fix it.

Regards,

やはり、変なパケット遅延がありますね。
これが全体の足を引っ張っています。

スイッチの問題のようかん。

Sean-san,

Thank you. I detected some other PIE servers have the same trouble.
I detected the same situation on banana601 and banana388.
But banana201 is probably normal.

I will also check the network performance on 2ch servers and I will
report to you the result sooner or later.

And I have an information. These banana601, 388 and tiger505 servers
have the same condition.

- network I/F configures 100Mbps full duplex
- 'incoming' traffic is no problem.
- 'outgoing' traffic is low performance now.

I think it may help you.

Regards,

さて、bananaは多いですね。

おかしいサーバ

他の掲示板banana(2ch/bbspink)は、とりあえず正常。
banana的正式名称は、、、。

qa = 386
etc3 = 601
live14 = 386
tmp5 = 390
comic6 = 388
food6 = 389
society3 = 382

I checked all servers for 2ch and following seven servers' network
performance is bad.

cobra: (There are no bad servers)
tiger: tiger505
banana: banana382 banana386 banana388 banana389 banana390 banana601

The situation of above servers are the same, the outgoing network
performance is bad.

Probably, I think their servers are connected the same edge switch.
Please investigate and fix it.

Regards,

Ok, I will do.

tiger505 修正確認。
他はこれから調査。

>>352 の全サーバのパフォーマンスが元通りになったことを確認。
障害は修正されたと思います。

経過観察で。

最近、この類の障害が続いてますね。。

Sean-san,

I briefly checked all following servers are OK.
Thank you for you work.

And I want to know how do you solve the problem.
Do you change the edge switch?

Seanさん、結構忙しいみたい。

で、私はこれから仕事で外出なので、またあとで。

はい、お疲れ様でした。

障害はSeanさんにより修復されました。
今は、正常のはず。
