I'm having trouble connecting to this website from home:

www.airliners.net

It works when I connect from work or via my phone and a few other places I've tried. I ran a trace route and here are the results:

It seems that the problem is at line 18, it always times stops there. Is there a way to notify the "people in charge" of this? I contacted my ISP but it works from their location. I went to DNS Stuff and ran the trace route there:

http://private.dnsstuff.com/tools/tracert.ch?ip=www.airliners.net

It mentions a firewall but other than that I don't really understand any thing else.

There's no routing problem at your end, so your ISP is unlikely to be able to help. If you look at the trace, you can see that, by hop 9 or 10, the route is out of AT&T's network and into Level3's.

If I try the same traceroute, I get to sjl01dr01-2-po1.demandmedia.net (your hop 18), although it's only hop 14 from where I am (I can get to Level3 within 5 hops).

However, none of this _really_ means anything, except to verify that it's not a routing problem at your end. When I get to the last hop, I get the "* * *" stuff as well.

The "* * *" stuff is caused by a firewall at the other end. The thing is: this firewall's allowing HTTP traffic through it (I can connect to the website), but it's not responding ICMP traffic, which is why traceroute stops at that point.

Thanks for the info. So basically there's nothing I can do at this point besides wait and hope that someone figures out that there is a problem somewhere along the line? Would contacting the owner's of site I'm trying to reach help?

So what exactly is the trouble ??

Probably not. Plenty of other people can reach the site, so they're going to say it's a problem on your end. And like Mark says: what exactly is the problem? What did you do? What did you expect to happen? What actually happened? What steps did you take to isolate the problem?

Or, to be more specific: What OS? What browser? What firewall or AV? What address did you enter? Do you have a proxy configured? I'll assume that you expected the page to display, so we can skip that part. Did you get an error message, or just a blank page? If you got an error message, what did it say? If you have access to another location, what happens if you try from there? What about trying a different OS or browser?

From my end, I'm on Windows 2003 SP2, running IE and Chrome (it works in both). My connection to the outside world is through a SonicWall gateway. I have no proxy configured. My AV (CA eTrust) doesn't monitor network activity.

Whoops!

I can connect from work, but not from at home is what I was trying to say....

The ISP is Atlantic Broadband. I'm using OSX with Firefox as my browser. I also tried it from another computer running Ubuntu at home with the same results. I've tried connecting on the Mac with Safari and Opera as well, same result. I have the site bookmarked to the forums section of the website, both that and entering in the main page address result in the same error.

This is the error I get from Firefox:



I have no proxy setup and the firewall is from the wireless router.

A couple dumb things to try:

- Try connecting via telnet (i.e., telnet www.airliners.net 80) and see if the connection goes through.

- Try using the IP address instead of the DNS name, as above

- Try using Safari instead of Firefox

Sometimes, these problems come down to nothing more than having bogus entries in your DNS cache or web cache or other such things.

I tried all of the above, nothing worked.

You may want to try decreasing the MTU setting on your own firewall/router/whatever you have.

You got another machine you can test it on?

Yea, I've got two laptops. One is running OSX the other Ubuntu. Neither of them connect to this website. I'll try a Windows box tomorrow.

Oops sorry. Didn't see that you had already mentioned trying it on both machines.

The wireless router doesn't have any URL filtering abilities enabled does it? Tried rebooting it? It does appear to be something to do with the router unless both your OSX and Ubuntu machines have the same software issue which is a little unlikely.

This morning the site loads up just fine! Thanks for the help everyone!
