Question

Website accessible from some locations but not others.

Asked by: studlyed

Ok, this is a strange IIS question.
We host multiple sites on one server, each site has its own IP address.
This one site though, hosts a subdomain site, well call it sub.site.com
As well as site.com
These 2 are on the same IP using host headers
This works fine every where we test  it, except, for Australia
They only get the first little bit.
This used to work fine and nothing has changed. I am thinking it is possibly a router problem, but they can access other sites hosted at the same datacenter with no problems, so that throws that idea out the window.
Does any body have any ideas on what could be the cause of this, and possibly a way to fix it?

go to DNS manager, then

apply the following to both sites.
locate the NS record, then increase(increment) SOA (start of authority) by 1

UPDATE SERVER DATAFILES.

let 72 hours go by for propagation

 

by: studlyedPosted on 2006-04-25 at 18:39:00ID: 16540318

thanks, i will let you know if this works. have you seen this before? and did this fix it?

 

by: Silvers5Posted on 2006-04-27 at 00:15:18ID: 16550635

this is an "Australia" side DNS issue .. they might not be resolving correctly your 2nd site domain

 

by: studlyedPosted on 2006-04-27 at 07:53:16ID: 16553422

it does it on both the primary (www) and the secondary (partners)

 

by: studlyedPosted on 2006-04-29 at 11:46:05ID: 16569778

they resolve to the same ip just fine, they just dont get the entire page.
It's strange, really strange. They get some of the pages on the other sites hosted on the same server. We are pretty sure that this is a server issue. But we can't pinpoint it. We changed the SOA as suggested above but it did not work. Also, they resolve just fine (both nslook and a ping comes up with the same ip's)

 

by: irwinpksPosted on 2006-04-29 at 11:52:14ID: 16569798

somewhere in the routing table of the Australian connection, your server info is not being passed OR not updated...Something that you may not be able to control.. How about writing your ISP and ask THEM to look into it.  What's the URLs? Can you post here?

I'm in Hawaii

 

by: studlyedPosted on 2006-04-29 at 22:28:02ID: 16571213

www.munsys.com
partners.munsys.com
www.webhitshostings.net
www.1924main.com

those are a few sites on the server
the munsys ones are the important ones.
thanks for your help by the way

 

by: irwinpksPosted on 2006-04-29 at 22:32:59ID: 16571216

You're welcome

www.munsys.com OK
partners.munsys.com OK
www.1924main.com OK

www.webhitshostings.net  cannot find server.

Double check your DNS entries for webhisthostings.net

 

by: studlyedPosted on 2006-04-29 at 22:34:12ID: 16571218

I was thinking it was possibly a route issue as well, so, I had them try other sites hosted from the same building, just different servers, and they came up fine, also had them do a tracert from their site to our server, and those came up fine, the highest ping was a 250ms at one router in the middle.

 

by: studlyedPosted on 2006-04-29 at 22:35:09ID: 16571220

sorry about webhits
its supposed to be www.webhitshosting.net

 

by: studlyedPosted on 2006-04-29 at 22:36:54ID: 16571221

I also got them to send me the source of what they receive.
Its strange, its only the first part of the htmlfile. The first couple of K.

 

by: irwinpksPosted on 2006-04-29 at 23:11:43ID: 16571261

that works/

U/C page

 

by: studlyedPosted on 2006-05-02 at 16:31:44ID: 16591806

we think that we may have found part of the problem
the router was completely loaded from people attacking all the sites....crappy.... also i turned up all the timeouts on asp/asp.net and session times for iis. i havent heard back from them, but hopefully it will fix it.

 

by: irwinpksPosted on 2006-05-02 at 16:35:58ID: 16591817

that doesn't sound good... perhaps they have an immediately solution to switch over.

 

by: studlyedPosted on 2006-05-06 at 10:41:11ID: 16622281

that wasnt the problem unfortunately.....
we upgraded the router and now things seem to be worse. now they dont even get part of the page. I am really thinking thtat this is a routerissue, they got worse with a new one. so the router is affecting things. what is your thoughts?

 

by: irwinpksPosted on 2006-05-06 at 13:10:35ID: 16622736

what router are you using?

 

by: studlyedPosted on 2006-05-08 at 08:16:44ID: 16631263

i'm not sure, i am only incharge of the mail/web servers. I will find out as soon as I can.

 

by: studlyedPosted on 2006-05-08 at 12:25:35ID: 16633495

its a netscreen firewall/router. It was just recently upgraded (more ram).

 

by: irwinpksPosted on 2006-05-08 at 14:38:15ID: 16634504

got the model #????  If you do, that would be helpful in reference settings.

 

by: studlyedPosted on 2006-05-08 at 16:02:21ID: 16635180

I will get that for ASAP, I am also having the router guy look in the logs again for anything strange with the site.

Thanks for your help so far

 

by: studlyedPosted on 2006-05-09 at 10:21:18ID: 16641130

NetScreen 5GT
Sorry for the little delay.
He looked through the logs, but didnt see any thing that stood out.

 

by: irwinpksPosted on 2006-05-13 at 08:50:12ID: 16674159

@studlyed...Hi, I just got back from a short vacation....perhaps their upstream provider can verify/correct the routing to that NetScrent 5GT

 

by: studlyedPosted on 2006-05-15 at 16:10:06ID: 16686529

sorry about the delay in response, been busy with my primary job. i will have a talk with them tonight, have to go overthere and talk to the people anyways. I will get back to you. I'm assuming you are talking about the upstream provider for munsys?

 

by: irwinpksPosted on 2006-05-16 at 14:18:37ID: 16694480

yes

 

by: studlyedPosted on 2006-06-07 at 13:23:44ID: 16856067

sorry again about the long wait. the problem was with the upstream provider. They didnt say what it was, just that it is working now. Thanks for your help

 

by: irwinpksPosted on 2006-06-07 at 13:26:28ID: 16856095

"They didnt say what it was, just that it is working now."
Ha!... somebody messed up and didn't want to admit it... ;-)

thank you!!
