579786 2007-08-12 00:46:00 What does this mean?

www.imagef1.net.nz

There is no problem with the net at all.
Just won't trace anywhere.

579787 2007-08-12 00:57:00 Looks like a firewall.

I get a non-response in one of the nodes when I traceroute to 58.28.13.49.

579788 2007-08-12 01:02:00 Nope, firewall enabled/disabled makes no difference.

It started after Xnet did something. Cause now quite often it takes ages to get Google up in the browser too.

579789 2007-08-12 01:09:00 Eh no.

Firewall on the machine that is unreacheable, not on your machine. Some can be set to block packets used by tracert/traceroute.

Xnet using a different route?

579790 2007-08-12 01:19:00 Hmm, strange... if I tracert to www.google.com it goes to www.l.google.com with IP address of 72.14.253.104... :illogical The_End_Of_Reality (334)
579791 2007-08-12 01:37:00 You can't really duplicate pctek's result unless you are running tracert from the same ISP (in the same location?).

Try tracing to one of the IP addresses in the jpeg pctek posted. You should see a no-response at one of the gateways.

E.g., traceroute to 58.28.13.49. The no-responder is at 10.

Probably a firewall, could be any other configuration resulting in a no-response, invalid response etc.

579792 2007-08-12 01:48:00 PCTek, what are your ping times like, could your TCP layer be nackered/corrupted, perhaps a winsocks fix? SolMiester (139)
579793 2007-08-12 03:41:00 PCTek, what are your ping times like, could your TCP layer be nackered/corrupted, perhaps a winsocks fix?

I did say there isnt a problem with anything.

Pinging Google gives 273ms. Thats about what its always been.


I just can't tracert anyone.

Nah, I think it's something to do with google, and not just today :dogeye:

579795 2007-08-12 04:59:00 Well its not my end.
I restored my PC image.

Trying to get google sometimes takes a while too is the other thing I've noticed recently.

Other than that, all is as usual.

Weird. I've emailed xnet about it.
