This should be fixed once the mirrors update within the hour hopefully :)

I have noticed a similar problem with redirects from the main php.net to a mirror. 
This happens when a 
user has set their preference to a cc.php.net mirror, or hasn't picked a 
preference.

For example, say a user has set nz.php.net as their preferred mirror:
$ curl -Ib "MYPHPNET=%2Cquickref%2Chttp%3A%2F%2Fnz.php.net%2F%2C0%2C" php.net/_GET  
| grep Location
Location: 103.6.212.224_GET

compared to one set to nz1.php.net:
 curl -Ib "MYPHPNET=%2Cquickref%2Chttp%3A%2F%2Fnz1.php.net%2F%2C0%2C" php.net/_GET 
| grep Location
Location: http://nz1.php.net/_GET

and one not set:
$ curl -I php.net/_GET | grep Location
Location: 103.6.212.224_GET

Yeah, I'm seeing that same behavior now.  The day I made the changes, I was not, 
even after testing numerous mirrors with as much randomness as humanly possible.  
I may need to revert some of the commits and devise another method for displaying 
the appropriate sponsorship information in the footer.

The redirection issue was repaired several days ago, and no similar problems have 
been reported since.  As such, this incident is considered resolved.

Thank you very much for your report.
