Tracert - Request timed out - how to read results?

Some users notified me that some websites stopped working in IE.

I used the tracert command to see the outcome. As an example below for nasdaq.com the time out comes always on the same routers.

How should I read this result?
It seems like the site is blocked to us. I checked from outside of our network and nasdaq works just fine.

Thank you.

Sometimes routers will drop tracert and/or ping packets on purpose so as to not be burdened with the extra traffic ... I've seen tracert results where a few in the middle show request timed out and then the last few pickup again and give valid results ...

OK.
Where should I look for the reason a website is not displayed.
I checked Chrome. Same story on every computer within our network.

TBK-ConsultingCommented:
try using pathping as well to see what it's results are and if the stops come in the same place or differently and yes it could be the site is blocked to you, the question tho is by whom, by looking at the tracert so far it is quite a few hops out there so it would not be the ISP blocking it but something further down.

Yes it appears as if Verizon is stopping the website for whatever reasons - who knows - are they your ISP??? if yes , send them copies of the tracert and the pathping and ask them why they are blocking, it could be something temporary like a major router down and that's the only route to that specific website thru their network???

maybe fibersonic is leasing lines from Verizon?  It is worth giving them a call and seeing if they know if anything is down above them which would be causing this problem ...

There are a something I don't understand in this case, I'll just list what I think.

1.traceroute results don't necessarily indicates a problem. It's a common practice to drop ICMP TTL Expired packet for security or whatever reason(make it harder to figure out the network structure)

Your traceroute shows fibersonic-->Atria Networks LP.(216.16.255.225)-->Cogent (from 38.104.251.181 to 154.54.10.226)-->MCI Communications Services, Inc. d/b/a Verizon Business(from 152.63.33.118 to 63.111.126.50), then the hop(receiving an ICMP ECHO TTL=0) dropped ICMP TTL Expired(no packet coming back causing Request Timed Out).

See attached my tracert 206.200.251.71
my ISP-->Level 3-->MCI Communications Services, Inc. d/b/a Verizon Business(from 152.63.33.118)
the slight difference on pos7-0.ur1.ewr2.web.wcom.net(yours is pos6-0.ur1.ewr2.web.wcom.net), I don't exactly know how that works but probably just choose a different hop for packets from different source

What I dont understand is your pathping www.nasdaq.com. Pathping and tracert and essentially the same thing, why your pathping stopped at 154.54.10.226?

Can you run pathping 206.200.251.71,pathping www.nasdaq.com,tracert www.nasdaq.com and tracert 206.200.251.71 again? They should be the same, or there might be a problem(maybe timeout settings? I haven't checked the default time out for tracert and pathing, you can try add some parameters to see if they make a difference)

(I find some hops may not reply to ICMP ECHO(regular ping), but they do reply ICMP TTL Expired so you can see it in traceroute )

Also can you run ping 63.87.242.37 -t for a while and post the results?
From what I see
ping 63.87.242.37 -t (Windows)
Pinging 63.87.242.37 with 32 bytes of data:
Request timed out.
Request timed out.
Reply from 63.87.242.37: Destination net unreachable.
Request timed out.
Reply from 63.87.242.37: Destination net unreachable.

PING 63.87.242.37 (63.87.242.37) 56(84) bytes of data.(Linux)

From 63.87.242.37 icmp_seq=9 Packet filtered
From 63.87.242.37 icmp_seq=11 Packet filtered

I used wireshark to capture packets from 63.87.242.37, and found
1. replies from 63.87.242.37 are ICMP Type 8(Echo(ping)) Code 13 (Communication Administratively Prohibited  [RFC1812])
So there is a firewall on 63.87.242.37 that denies echo which explains no further path info are shown.
2.63.87.242.37 doesn't reply every echo, smart firewall policy to avoid flooding attack or the hop does have problem(losing packets)


154.54.10.226(epoch.sjc03.atlas.cogentco.com) is an ip address from ARIN. From the dns name it's owned by Cogent Communications, a US network backbone company. They probably just bought some IPs from ARIN for whatever reason.
154.54.10.226      United States      District Of Columbia      Washington      Cogent Communications
Whois doesn't necessarily say the geological location.

Nasdaq.com(probably entire 206.200.250.0/23) doesn't reply ping.

From the dns name verizon.iad01.atlas.cogentco.com(154.54.10.226), it's a route from Cogent Communication to Verizon, owned by  Cogent
The reason you can only reverse resolute 154.54.10.226 is there is a ptr record for 154.54.10.226, but   dns query for verizon.iad01.atlas.cogentco.com gets a no such name reply code 3. I don't know a lot about DNS. maybe security policy...


I don't know how 75.125.82.251(dnsstuff.com web server) is related to this problem...

And BGP and AS
Destination is
206.200.251.71
United States
206.200.250.0/23
AS14495
NASDAQTRM The Nasdaq Stock Market


The last traceable hop is
63.87.242.37
United States
(none)      63.87.224.0/19
AS11486
WAN Worldcom Advance Networks

AS14495 is connected to AS11486 WAN Worldcom Advance Networks(some information:http://www.robtex.com/as/as14495.html#peer), unfortunately I know little about AS and BGP
You might be able to figure out how the packet reaches the destination after 63.87.242.37 with some analysis on BGP/AS.

From another aspect:
1. what other websites don't work( the route goes through AS11486 as well?)
2. try other browsers? chrome/ opera?
3. try other os
4. how are the users experiencing this problem distributed(same subnet)?
5. so you mean some users can still access nasdaq.com, how's the tests(traceroute) at those users like?
6. i think it's likely to be local access restriction. since Nasdaq doesn't allow ping, it makes troubleshooting harder but capturing packets still helps a lot(ping results can be misleading like I posted ping results above, but packets tell you the true story)
7. try to contact nasdaq? the problem may be on their side, not necessarily blocking but misconfiguration(CDN etc.) can definitely cause this problem

Good luck and thanks for the case I reviewed so much network knowledge :)

Thanks for the test. These 4 tests are exactly as expected(last hop 63.87.242.37: and packet filtered as I said above). The route seems ok, at least from your side to 63.87.242.37.It might be easier to think about those questions at the end of my last reply. :)
