Unable to access web site http://www.baidu.com

Within the last 2-3 days the site http://www.baidu.com stopped working. Traceroute yields the following:

C:\>tracert www.baidu.com

Tracing route to www.a.shifen.com [119.75.216.30]
over a maximum of 30 hops:

1 4 ms 2 ms 2 ms Wireless_Broadband_Router.home [192.168.1.1]
2 7 ms 7 ms 7 ms L100.BSTNMA-VFTTP-147.verizon-gni.net [173.48.{edited for privacy} ]

3 119.75.216.30 reports: Destination host unreachable.

Trace complete.

Located in Sudbury, Massachusetts.

Anyone else experiencing the same problem?

Thanks!

I am in Texas and cannot get to that site either. Do you know for sure the site is up and working? It could just be down (for days, a site I support was down for almost 4 full days a few weeks ago due to a virus problem).

This may (again, may) be your problem: I see you have a173.48.x.x (you really should x-out the last two octets of your IP address for privacy reasons), I am on a 173.74.x.x address; I know some people have had problems with getting to some sites now that they have a 173.x.x.x address. I think Verizon obtained addresses in that range and some of the addresses apparently previously belonged to spammers or some malicious folks.Some sites (web sites, intermeidate routers, etc.) blocked those addresses, and may not have updated their filters to remove the block on those addresses because they don't know that Verizon now owns them. If this is the problem, eventually those filters will get updated and you will be able to access the site, but this could be a fairly long time.

If you know how to contact that site I suggest you email them about the problem. You can also try turning off your router overnight and when you turn it back on the next day you may find that you have a different address (one that doesn't start with 173) that will allow you to get to the site.

I don't think there is much Verizon can do to help, it is not their site that is blocking your address (at least I don't think it is).

Hope this helps.

I am currently not on a verizon fios connection, and can also not get to that site by IP or domain, or even the secondary domain listed in your tracert

sounds like an issue with the site specifically

sjmorton

Thanks for the tip, I'll try shutting down the router tonight. The site is definitely up since I can access it from work. It's the Chinese Google so I don't think I'll get much attention if I try to contact them 🙂

Thanks again!

You may be right about not getting much attention if you contact them. Smiley Very Happy But you could try to contact them from work, maybe they can suggest a work-around.

If I can remember (getting harder and harder the older I get....) I will try to access the site tomorrow when I am up at our lake house where we have AT&T for internet access, and I can also try via the local cable company up there. All I have to do is remember, remember, remember...

Good luck getting this working. No guarantees on getting a new IP address by turning the router off, but you just might, you never know.

Simon,

I can get to the site just fine from the local cable system rather than using FiOS. So that makes me pretty sure it is the IP address you have that is being blocked.

Simon,

Just to complete my testing I accessed the site just fine from an AT&T DSL connection. Did you have any success getting a new IP address? And if so were you able to get to the site?

Mine went through fine. I am just North of Washington D.C. . Perhaps Washington has a direct route to China. No web site comes up on that domain. Or the NSA has filtered it. I have always questioned what the private 10.x gateway does. Smiley Very Happy

Target: www.baidu.com
Date: 6/16/2009 (Tuesday), 8:03:10 PM
Nodes: 5

Node Data
Node Net Reg IP Address Location Node Name
1 - - 192.168.0.5 39.171N, 77.273W HOMENET1
2 1 - 192.168.0.1 Unknown
3 1 1 192.168.1.1 Unknown wireless_broadband_router.home
4 2 - 10.1.41.90 Unknown
5 3 2 119.75.213.61 BEIJING (PEKING) www.baidu.com

The above trace comes up every time with a program called NeoTrace. But with a standard tracert at the cmd prompt it times out right after the default gateway. Looks like someone does not want us to hit that server.

What are the first two octets of your IP address? I am guessing not 173.x. I really think it is a bogon filter somewhere that has not been updated to allow the 173.x.x.x addresses Verizon is now using to get through (but of course I may be totally wrong).

Anyway, I cannot get to the site from my FiOS address but I can from a cable connection and from AT&T DSL, both of which are not 173.x.x.x addresses.

I got to the site using FIOS with no problem. All I had to do was reset my router and restart my browser.

True. Could be one of those Canadian IPs. I was lucky and was issued 96.255.4.X and used to get IPs in a lower class A subnet. But when the 173s started being issued trouble came up. Strange that whenever I do a trace from the cmd prompt it times out at the gateway. Perhaps I will do a lookup of the domain and see who the registar is.

You were probably issued a new IP.

nycrdc

FIOS DHCP (173.x.x.x).

The IPs seemed to be mapped to France in several Geographic IP databases.

Yep. He is most probably on a DHCP connection and can get a new one fairly easily. Since I have had FiOS internet for 4 years now I am still on the original PPPoE connection. My IP address changes very infrequently. I think I have had maybe 4 or 5 different addresses in the 4 years, at least once a 64.x.x.x I think, the last three have been 71.164.x.x and two with 173.74.x.x (not that I really care, other than some websites thought I was in Kansas City or St. Louis at one point due to the address I got).

Anyway, I hope the OP was able to get the connection he wanted.
