HTTP/1.1 503 Service Temporarily Unavailable

It’s the English version of http1.1 503 service temporarily unavailable, for the people who came from English Speaking countries.

Not long ago, I met HTTP/1.1 503 Service Temporarily Unavailable while I was using “fopen” to open a long-distance page, then I was thinking whether my sites run out of some limits, but the online operator told me that’s not the server’s reason. 继续阅读HTTP/1.1 503 Service Temporarily Unavailable
