timeout problems at JPC

**btimms** · 10-18-2006, 04:49 PM

I'm looking for suggestions/ideas and remedys to consistant browser timeouts with accessing anything JPC- including the homepage and support pages not to mention my site(s). No support problem as they have been responsive with good insight. Started with timeouts earlier this week on the hoth server. Contacted support and they said it was overloaded and moved me to martin. This works fine most of the time but every couple of hours or so every site times out for anywhere from a few minutes to a few hours. In addition every JPC page times out including their support,homepage, and this forum. Other commerical (yahoo, google, etc) sites work well as expected. Here is the kicker - I can go to one of the anonymous proxys when I'm having these problems and access my sites and all JPC sites fine - so its got to be something between me and JPC. I'm just outside of Atlanta and am using charter.net as isp currently but the same thing has happened on bellsouth.net. I also have tried in on several machines including disabling firewalls etc. Any suggestions or comments would be appreciated.

Thanks

First thing I would do is ping your site a hundred times, and see what it says. For instance:

Code:

ping yourdomain.com -n 100

Then, I'd do a trace...

Code:

tracert yourdomain.com

If those look okay, I think I'd try using different DNS servers in your browser. Another trick I've learned, that works a lot of the time, is simply switching the (ISP's) primary and secondary DNS servers around in your browser.

If you know how to do lookups, I'd try that too...

Thanks - pretty much tried ping and tracert - when I start getting the timeouts both ping and tracert timeout also as expected. When the browsers not timingout ping works fine with 10ms times but tracert timesout constistantly after 10 hops. I'm going to experiment with some public dns servers and hopefully will be able to nail it down.

Any other ideas appreciated.

Thanks

Sure. Download the WinMTR binary to your PC from:
http://winmtr.sourceforge.net/

Run it for your domain, see where the time is being spent along with packet losses or whatever is happening. It runs in a loop and shows last, best average and worst times, and also shows percentage of packet loss at each hop.

It was recommended to me once by support here at Jag.

Ron - cool tool - wow.

I changed my dns srvs to the local colleges - Ga Tech and U of GA and things started blazing. I'm going to change back to my old dns later on and check winmtr - right now its not missing a beat.

Thanks

Hey, that's cute! I'll have to try it out.

**btimms** · 10-19-2006, 12:24 PM

Well, things have gotten much worse. I can't access any site on the JPC network - my sites, jaguarpc.com, and this forum site (I'm currently using an anonyomous web surfer which obviously uses a different route to get here). Below are results of using WinMTR with http://jaguarpc.com as the target site captured at 1720 packets. Its been consistant like this all day. I can access any other site on the internet other than JPC related. I've posted to support but they have not had time to respond yet. I'm going to try to get some support from the ISP but am not expecting much. Any suggestions would be GREATLY appreciated.

Atta boy!

I haven't used my ISP's nameservers in a long time!

**btimms** · 10-19-2006, 12:36 PM

I saw that. However, because I all can access all JPC sites including mine through an anonymizer I think its something else. It would be logical if they were just my sites but JPCs home page and this forum cannot be accessed either.

Thanks

Was your machine infected with a virus and causing a UDP flood before? Perhaps Jaguar has blocked your IP address?

Send in a ticket to support...

**JPC-Les** · 10-19-2006, 12:46 PM

Looks like a peering issue outside the control of our Datacenter but We'll get a ticket opend with the network guys at the DC and see if they can get with the folks in charge of those routers where your timing out and let them know they have a problem.
