折腾:

[记录]不同网络测速以便于给Linode的VPS更换速度更快的服务器

后,决定去让客服给我从

Singapore, SG

换到Fremont

please change VPS from Singapore to Fremont
Hi Mr/Mrs,
    My VPS server is current on Singapore node, which speed is become quite bad, too slow, especially UNABLE to access it, from my current location. My network supplier is China Telecom, Jiangsu Province, current speed from here to  my Singapore VPS server is extreme slow, most case can NOT access the server.
And I also goto:
https://www.linode.com/speedtest
to test the speed for other network supplier, such as China Unicom, and the speed is also not stable: some time good, some time very bad, can not access.
but after my so many time tests, the speed to Fremont server is relatively stable, even if some time is still not good, but at least CAN access it, can connect to it.
So, my request is:
Please change my VPS server node from current Singapore to my expected Fremont.
BTW:
if possible, please do more optimize for Chinese region access speed to your server,
especially for different network supplier, China Telecom and China Unicom, from SuZhou, Jiangsu to VPS node of Singapore and Fremont.
Thanks.
BR,
Crifan Li

 然后就是等待回复了。

结果其回复太快,我没注意,然后过了2天,其主动关闭了。。。

所以只能再去提交申请。。。

Hi Mr/Mrs,
Following is my previous ticket request:

and also has got responsively reply:
++++++++++++++++
Hello,
Thank you for contacting Linode Support. We can certainly perform this migration for you to Fremont. Before we can configure this, please note the following :
– Your IP address will be changed
– You will experience 10-15 minutes of downtime per GB of data migrated
If this is fine, please let us know and we can begin the process.
++++++++++++++++
But due to my delay reply, after two days, the ticket has been closed.
So, my new request is:
I already has notice changing VPS will change IP and experience some downtown time.
So, please change my VPS from Singapore to Fremont, WITHOUT my reply !
Many Thanks.
BR,
Crifan Li

等待回复。

最近的VPS服务器不稳定,无法访问,都导致别人在知乎上找我问是啥情况了:

真快,没几个小时,就已经回复了:

Hello,
Your migration to our Fremont datacenter has been configured. Please log into the Linode Manager, shut down, and click the migrate button to move to your new server. Your disks will be moved with you. The migration should take approximately 10-15 minutes per gigabyte of data to complete. Please note that any existing backups for this Linode will be purged and will not be recoverable after you initiate the migration.
Your new IP address is: 45.79.93.175
We ask that you begin this migration within 24 hours and let us know when it is complete. Thanks in advance!
Regards,
Karen L.

按照提示去操作

并且搬家完成后,及时回复人家。

自动断开,重新登陆

点击:

Migrate to fremont831.linode.com Now

重新登陆

但是现在郁闷了:

网站

https://www.crifan.com

无法打开。

虽然可以ping:

licrifandeMacBook-Pro:~ crifan$ ping www.crifan.com
PING www.crifan.com (139.162.21.142): 56 data bytes

4 packets transmitted, 0 packets received, 100.0% packet loss
licrifandeMacBook-Pro:~ crifan$ 

可以注意到,www.crifan.com的地址是之前的。

所以去直接访问IP:

licrifandeMacBook-Pro:~ crifan$ ping 45.79.93.175
PING 45.79.93.175 (45.79.93.175): 56 data bytes

round-trip min/avg/max/stddev = 193.706/195.374/197.992/1.636 ms

可以ping,但是还是打不开网站:

http://45.79.93.175

过段时间再说,或许是搬家后,IP不稳定?

结果其后几天,都还是无法访问www.crifan.com

然后去:

Last login: Fri Apr 15 20:49:44 on ttys009
licrifandeMacBook-Pro:~ crifan$ ping www.crifan.com

<div–<- www.crifan.com ping statistics —

6 packets transmitted, 0 packets received, 100.0% packet loss
licrifandeMacBook-Pro:~ crifan$ 

想到了:

好像是需要去更新DNS服务器的?

去吧IP地址更新一下:

然后去找到64位的IP:

再去更新64位IP,从:

2400:8901::f03c:91ff:fe18:5238

为:

2600:3c01::f03c:91ff:fe18:5238

然后等两天看看效果。

感觉是:

由于没有及时更新IP,导致虽然可以打开:

http://45.79.93.175

但是非常非常慢,等了半天,终于打开页面了,但是是乱的:

-》估计是内部很多资源还是www.crifan.com的旧地址139.162.21.142上面的,所以打不开,所以很慢

-》等抽空DNS生效了,www.crifan.com就可以解析为最新的45.79.93.175,估计就正常快速打开了

-》到时候去确认。

如果还是慢,再想办法,实在不行,考虑换VPS,甚至是换到国内?

但是看到了:

中国网站备案制度——祸国殃民-卢松松博客

还是算了。。。

打死不用国内的。。。

更新DNS的半天后,再去访问网站,已经可以正常访问了:

然后去ping,IP地址也的确是最新的了:

licrifandeMacBook-Pro:~ crifan$ ping www.crifan.com
PING www.crifan.com (45.79.93.175): 56 data bytes
64 bytes from 45.79.93.175: icmp_seq=0 ttl=51 time=344.305 ms

64 bytes from 45.79.93.175: icmp_seq=4 ttl=51 time=351.312 ms
^C

<div–<- www.crifan.com ping statistics —

5 packets transmitted, 5 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 344.305/349.933/352.207/2.934 ms

-》

虽然ping有点高,不过实际上网站访问速度还不错,基本上也不用等待,网页就可以打开了。

-》这才是正常的网站访问效果嘛,?

【后记 2017-07-02】

后来的后来,还是觉得Linode的VPS的服务器,虽然速度不错,但是估计是国外访问速度,国内访问,还是不太好,然后最后换到了朋友的服务器上了:

【记录】crifan.com服务器换到fzhost.net
