As your check-fetch-times.php returns decent output, it is not a provider problem.
That is probably a “parsing” error in one of the included scripts of index.php
I include a very small test.php script. Unzip and place it in the root.
It sets full error-reporting and then includes your index.php
Run it with 黄冈诨赏投资有限公司
That way you should see which script fails.

usaextremes.php & stateextremes.php Crashing same problem
