A site I frequent (vbforums.com) has been very slow to me since Friday and when I try to ping it I am getting TTL expired on transit and tracert gets me the following result:

I can access all other sites fine except vbforums so I am wondering where the problem lies. It seems other members of that forum does not have a problem accessing the site. Thanks for any help!
 
There is a routing loop between 202.138.166.173 and 202.138.166.174. Whoever controls that network is responsible for the problem.
 
What do you mean "Whoever controls that network"? You mean the website owners, my ISP or what?
 
I mean precisely what I said. Someone is responsible for the administration of that netblock you listed. It might be your ISP, it might be the site that you're trying to hit, it might be someone in between.

Here's the WHOIS information for the netblock with the routing loop:

If this is your ISP, you may want to contact them and ask them about this behavior. Otherwise, there's not much you can do. If the problem is on the site's side, they'll notice soon enough.
 
Well, that is my ISP. So it looks like the problem is on my ISP then? Sorry, don't know a thing about this problem. =(
 
It sounds like the problem is with your ISP. You'll want to contact their technical support and send them the output of the traceroute you posted earlier.
 
Is it not odd that when I used another computer with the same ISP I could access the said site?

Not really. ISPs generally have connections to multiple independent carriers for performance and fault tolerance purposes. The other computer could be taking a different path through your ISP's network.
 
I'm wondering, can I bypass that loop and be able to access that site using a proxy or something?
 
I've seen this happen before. You'll want to contact your ISP but chances are their NOC will have seen it and their help desk is probably getting more calls.

Does not hurt to call them with the details though, just in case.
