How to check whether the server IP is queried by the wall

Some online tools can be used to determine whether the foreign dedicated server IP is blocked. These tools usually send ping requests or HTTP requests to the target server, and judge whether the server can be accessed according to the response time or status code and other indicators.

Here are some common online tools:

1. Ping.eu： https://ping.eu/ping/
2. DownForEveryoneOrJustMe： https://downforeveryoneorjustme.com/
3. IsItDownRightNow： https://www.isitdownrightnow.com/

If these tools show that the server cannot be accessed, it may be faulty or blocked. However, it may also be caused by other network problems, so further investigation is needed. You can contact your server provider or network service provider for more help and support.
