搬瓦工是不是挂了，从昨天到今天， IP 地址可以 ping 通，但是梯子挂了

是的

@slfmessi 那申请更换 IP 地址？

我的一个 DC3 的也挂了，建议更换 IP 地址吧，客服的回复是：

Hello,

Looks like the IP is blocked by GFW. While the IP is on any other major block list (Spamhaus, Barracuda, GFW etc), the VPS stays fully operational. However you will not be able to migrate the VPS to a different datacenter until the block is removed.

Here is how to verify if your VPS IP is being blocked by the Great Firewall of China:

1. Navigate to http://tool.chinaz.com/port/
2. Enter your VPS IP in the top field
3. Enter your VPS SSH port in the bottom field
4. Click 'Start scanning'

The service will attempt to connect to your SSH port from China and in case of banned IP will show that the port is closed.

Then, you can do the same test from an ISP outside of China, for example:
https://www.yougetsignal.com/tools/open-ports/

If you try performing same test from outside of China, SSH port will work - you will see a message:
'Port XYZ is open'


*** Possible solutions ***


We found that generally GFW automatically removes the ban when it can no longer detect the 'prohibited' service for a few days to few weeks. The best solution in the case of a ban would be the complete removal of all service(s) that could trigger the ban and waiting for some time for the ban to be lifted.

Having said that, please do keep in mind that we do not have any control over GFW, and we do not know much about how it works. It is our responsibility to make sure our hardware and network stay fully operational, and GFW-related issues are out of scope of our competence.

If you need to replace a banned IP with a clean IP, there are two options available to you:

*** Option 1 *** Free IP replacement. We allow you to replace a blacklisted IP with a clean IP for free, once every 5 weeks. To access this feature, first login to KiwiVM as usual, then access the following hidden page (copy+paste link into the browser's address bar):

*** Option 2 *** Manual IP replacement (fees apply) available at the following link:
