Rad,
The trace you posted shows a network slowdown in a different place than the other guys. They seem to be seeing a slow down on a Cox router (lvcm.com) while your first hop with high response time is AT&T. I don't think we can assume they are part of the same issue. We'll need to see more tracerts for the other guys, but it looks like Cox has some overloaded routers in Vegas.
If you guys can post a few more tracerts, we can contact Cox about our concerns.

Hi.
I don't want to come off saying that it is your ISP but hops 6 and 9 show that the routing from your ISP is having latency.
6 shows 219ms at the att.net router 9 shows 231ms which the router won't resolve the location.
Our network is cust-lunarpages.marquisnet.com and of course hafgan the server your account is on.
The culprit unfortunately is hop 6 this is where the packets get lost. I can not speak for your visitors since I am not aware of their routing or if indeed they are routed through ATT as well. .
I have a site that I frequent to check network routers which I can not vouch for their accuracy but it gives some indication of what may cause connection latencies on the internet.
http://www.dslreports.com/routerwatch
It is handy enough that your visitors may want to check to see if any of their ISP network are affected by these routers.

Same problem again this morning at 6:28 am Pacific Time (from LA/Orange County area).
Got 3 IE cannot display this page messages so far. Response time about 5-10 seconds for most screens. During the day, response time is instantaneous.

It looks like the problem hop is hop number 9 in your latest trace. Looking back at yesterday's trace, it looks like this same hop had and error. Since its an AT&T IP address, I'm guessing its the customer side (Lunar Pages) of an Internet Circuit provided to Lunar Pages by AT&T. If this circuit or the router it is on is maxing out in the mornings, that could be our culprit.
Based on the traces provided by Ghost4me, his traffic takes a different route and doesn't go through AT&T. Since he has the same issue at the same time, I would guess the circuit is not the issue, leaving me to suspect the router.
We could easily detect if the router is overutilized. Next time this happens, we need to ping this router. That is 24.234.18.130 for NightOwl and Ghost4me and 12.118.228.38 for Rad. I'm assuming these two different circuits terminate on the same router, which is common practice. Routers process ping replies as a very low priority, so pings to this router should be noticably higher than pings to the radified server if the router is overutilized. If not, we'll have to go back to the drawing board.

Some but not as many pauses this morning (6:30am PDT). Maybe everyone is on vacation or weekend.

yesterday, i twice got "unable to display this page" errors. in the afternoon. could not to connect to *any* page on the site.
hit refresh like crazy .. no joy.
problem only lasted a few minutes. by the time in called the LP sppt number, the site was back.
duriung this time, i *could* ping the site (nice numbers), and could ALSO access both email abd the site via FTP. (It's like Apache was down intermittently.)
I sent email to LP. Their response:
Ticket Subject : slow response times?
Reply:
Hi.
I will need to escalate your ticket so that this can be investigated further. It appears at times that the issues lie soley with the routing and at other times it appears from the posts on your forum that the routing plays no part in it.
I have made notes to this ticket and hopefully when investigated further may prove to be helpful in providing a resolution.
Kind regards
[These guys are the experts.]
EDIT .. And posting this message gave me the same error. A retry worked fine. Never had any such problem at the old server (the one in LA).
here's a trace, done just now (26may 9:25 AM PST)

Everything is normal right now (10:30am PDT). However, look at this PingPlotter I just completed:
It appears, as I read it, there was 33% packet loss at the router just before their server. This is the one that MrMagoo suggested we look at.

Here's another 15 sample PingPlotter 30 minutes later than the first one.
14% packet loss over 15 samples.

i see that.
otherwise, those numbers look good. thanks for helping to troubleshoot.
i wonder why my *gifs are 25 KB, and yours are 95.
today LP assigned my dedicated ip (finally, after a surprisingly long delay). that might help (tho probably won't).
i might add here, that my radified email-checking (i have a dozen accts i use, outlook express) is *blazing* fast. fastest i've ever seen. not sure what that might mean. but still a data-point to consider.
when i *do* get the site, it seems smokin' fast.

I noticed the same thing when I posted the images. The first one was a jpg, and I experimented with saving as a gif. (I'm using PhotoShop Elements 5.0) The image is 36K on my hard drive, so I don't know why it's 95K on the webpage. ??

i use photoshop cs3 > "save for web" *gif.
elements i believe is more for *pictures*. right?
your (gradient) xp-style title bar might be causing problems there. (i use "classic".)
