Topic # 13654 22-May-2007 11:23

I'm trying to order books from amazon.com, the pages are timing out. I called TC helpdesk, someone who didn't know anything about the internet answered, and said I can hold for an hour to talk to tech support or they can call me back on Thursday. Very helpful TC, great going.

The lady on the phone could browse amazon.com fine. I can connect as I get the page titles, but if I get the page body it takes ages - 15 minutes or not at all. Is anyone else having problems connecting to Amazon.com?

Here's my traceroute - my IP removed.

On TelstraClear here, and Amazon.com works fine for me. Perhaps you have changed something on your router, MTU configuration, firewall rules?

I found an anonymous proxy and used that for my order - over https of course. Once I turned the proxy off amazon.com was working normally. No idea why. This happens quite often for me on TC.

traceroute is unreliable. In particular, since TC use transparent caching, traceroute does not tell you the real path for web pages. Try lft and see what it says (it's way better anyway). http://pwhois.org/lft/

They don't have a windows binary, and this machine isn't set up to build whatever language it'll be in. Not sure cygwin's installed either. Do you know an easy way to get an x86 XP binary?

Well, you can try the commerical Path Analyzer Pro in evaluation mode for a while I guess. Sorry, I don't know of any prebuilt Windows binaries.

How about www.ups.com ? It was working earlier in the day, now it won't load. Alertra.com says it's working fine. I'm getting really sick of TelstraClear not being able to give me websites that work through other providers, having to use anonymous proxies is a pain.

You should see the trace from path analyser pro... it goes via the US, hops all around, then goes to Brazil and back! Image below.

Apparently there are multiple DNS entries, I tried the 2nd by IP and it worked. Then I tried the first by IP and it worked. Then I tried UPS.com by name and it worked too. Something's really buggered in the TelstraClear system.

When I called TC they said I had to wait in a phone queue for an hour or more, or they'd call me back in 2 or 3 days. That's just amazingly bad customer service.

Interestingly, amazon.com still isn't working directly, but works via an anonymous proxy. That connection's routed through hong kong, philedelphia, then to washington, but seems to get lost somewhere inside the Level3 facility in LA.

If the person from Telstra Clear who posts here sometimes can get hold of me that might be nice. Or just fix the network.

% host www.ups.com
www.ups.com is an alias for www.ups.com.akadns.net.
www.ups.com.akadns.net is an alias for www2.ups.com.edgekey.net.
www2.ups.com.edgekey.net is an alias for e455.b.akamaiedge.net.
e455.b.akamaiedge.net has address 125.252.213.243

OK, that's means it runs through Akamai (which plays games with the DNS entries to point you at a local server). In other wirds, when you go to www.ups.com you are actually going in the first instance to a local server somewhere in Auckland, run by Akamai.

Thats really quite impressive... according to you Telstra run the internet.. THE WHOLE INTERNET!!

Once it leaves their network they have no control over how the traffic gets to the site that you have put in your web browser.

Suggest you look at Introduction to TCP/IP

I understand TCP/IP, maybe not to the level I could build a router, but I learned it in uni. I know TC might not be the cause, but they have the staff to diagnose the problems and work out what's up.

I'm starting to suspect that the issue is with dns lookups, given that I seem to have the most trouble with large sites that will have many servers or use Akamai. Looking up my UPS link again failed by host name, but by IP it worked perfectly.

When I try to get to amazon the traceroute bounces around one server in the level3 facility up to a TCP TTL of 60 but doesn't go anywhere or service the request. www.ups.com resolves to 192.168.105.2 - I thought all 192.168.* addresses were reserved for use inside networks? Or do I have the class A/B/C thing confused? I can also ping www.akamai.com but I can't see their website as it times out - ironic?

I just want to track this down now, I don't like problems getting the better of me.

Can you do a IPCONFIG /all and post that up. Might give some clues

Correct. 192.168.0.0/16 is part of RFC 1918 address space. You might well find private address space on a traceroute, but if the DNS is resolving to that, then something very odd is going on. Unless you have a very interesting NAT setup, it shouldn't work at all.

I have my PC plugged into the Linksys router/switch, which is plugged into the modem - so a fairly standard setup.
