The reasons for and solutions to the intermittent inability to access overseas websites such as 港台 and 美国.

```html

Fault symptom:Sometimes it is accessible, sometimes it is not accessible. In addition, when it is inaccessible, ping IP may be unreachable, and then becomes reachable again after a few minutes; and it may cause other websites on the same server in Hong Kong to be inaccessible,

When accessing, it indicates that the connection is reset, or after a long period of no response it indicates response timeout.

The above symptoms, after our company's long-term, extensive analysis of different sites, are caused in the vast majority of websites by the following two reasons:

1. Blocked by gfw due to website content reasons
How to check:When a page contains illegal keywords, or the website content itself has problems, the connection will be directly reset by gfw when accessing.
Solution:https://gist.github.com/zythum/2848881 Check against it whether illegal keywords are included; delete them, or completely change the website content.

2. Domain blocked by gfw
How to check: Check whether your domain is blocked. The reason for being blocked can basically be determined as the website content having problems, or the website content of this domain previously having problems.

Solution:First check whether your own website content has problems, handle the content problems first, then change the domain; or complete ICP filing and upgrade to a domestic host (but note, if it is blocked, it is possible that this domain still cannot be used even after upgrading to a domestic host).
