    try tracert 208.71.106.61 to determine how far you can go

    RESET is from the webserver it self :(

    and this shows your ISP (sbcglobal.net) can not access the next node in the path to
    208.71.106.61

    eg: not your fault and there's nothing you can do about it.

    If I ping ancho, it gives me 208.71.106.61 as the ip address, but if I tracert that ip, it displays hps13.fc2.com. What does it mean? Is this something I cannot do anything about?

    Edit: Just saw your 2nd post. Thank you so much for the help. I learned a lot.

    the address 208.71.106.61 belongs to FC2.com

    we do two lookups; one by address and the other by name
    Code:
    C:\Documents and Settings\Jeff>[B]nslookup 208.71.106.61[/B]
    Server:  dns-cac-lb-01.rr.com
    Address:  209.18.47.61
    Name:    [COLOR="Blue"]hps13.fc2.com     <the associated name[/COLOR]
    Address:  208.71.106.61
    
    C:\Documents and Settings\Jeff>[B]nslookup hps13.fc2.com[/B]
    Server:  dns-cac-lb-01.rr.com
    Address:  [COLOR="Blue"]209.18.47.61  < the ipaddress of this name[/COLOR]
    Non-authoritative answer:
    Name:    hps13.fc2.com
    Address:  208.71.106.61
    A ->points to ->B and B->A; ergo the dns has not be poisoned and the results are correct.

    My guess: sbcglobal.net ./ AT&T Internet has that server IP address blocked / banned

    Yes, I have AT&T. I guess that answers the question. Not the answer I would have liked, but at least I know there are no issues with my router. Thank you

    @jobeard: ancho = AT&T sneezed.

    I had some idle time and was curious to have one more look! I don’t know this will help but at least provide what I found.. Though maybe you can present your own case to ATT Helpdesk with proof to see if they’ll help (or at least acknowledge it's an ATT issue)

    1. Re: The other person with ATT and the same routing problem to 208.71.106.61
    > Their chat with AT&T Helpdesk
    > Their post to a forum
    Of course, ATT Helpdesk denies its their problem and tells them to contact the domain provider. But...

    2. I remembered i also have remote access to a machine using sbcglobal.net. So, i remote connected and ran routes to:
    > ancho.web.fc2.com [208.71.106.61] (which fails)
    > pi3141592c147.web.fc2.com [208.71.106.39] (which works)
    > fc2.com [208.71.106.124] (which also works)

    It looks like swbell.net (Southwest Bell) is the upstream router to sbcglobal.net. (Try these routes yourself.) When the route fails, it's failing within the ATT network!. It may be futile but if you sent ATT Helpdesk the traceroutes maybe they'd at least agree it's their routing issue? and hope against hope they might fix it?

    To be honest I'm reluctant to deal with large corporation tech support for the reason you cited. The games I'm trying to access usually get mirrored somewhere I can get to in a few days. It's more fun to play at the same time everyone else is, but I can always play later.
