Website unavailable through one connection but reachable through another

[azfar-adib]

I have been trying to access the site EXIM Bank Ltd through two different EDGE data connections provided by two GSM operators. For operator 1,the site does not appear. But for operator 2,it appears.

Interestingly, when tracert to this site is performed, the traceroute results are exactly same for both operators. In both cases, trace stops at the same hop. (Tracert results are given at the end of the post).

It is mentionable that for Operator 1, the site can be viewed while accessing through Opeara web browser. As per the question of this site is concerned, the site administrators have told that they are not blocking any particular source IP.

Can anyone please let me know , why this site is not fully accessible through Operator 1 while it is accessible through Operator 2?

Thanks in advance.

Line 6 of the first list shows an asterisk instead of a response time.

Could that signify something? Unreliable or intermittent response? But still able to do a hop?
