For testing purpose, i have added only few prefixes :-

geo {
default 0;
include geo.conf;
}

geo.conf

39.49.59.0/24 PK;
110.93.192.0/24 TW;
110.93.192.0/18 TW;
117.20.16.0/20 TW;
119.63.128.0/20 TW;
202.163.104.6/32 ARY;
203.124.63.0/24 CM;
221.132.112.0/21 TW;


Now, whenever some ip from the list send request, nginx reply with gateway
timeout :-

curl -I  http://files.com/files/videos/2014/06/10/14023918368e3411-240.mp4
HTTP/1.1 504 Gateway Time-out
Server: nginx
Date: Thu, 19 Jun 2014 19:59:50 GMT
Content-Type: text/html
Content-Length: 176
Connection: keep-alive

In order to resolve this error, i have to manually remove a network from
the file which is 110.93.192.0/18 TW;

What so suspicious with this prefix 110.93.192.0/18 TW ? Why it is causing
to crash every other requests ?
