Failing to ping an IP / DNS from all sources due to timeouts at various hops.

Does anyone way smarter than I know why this tracert fails from most computers.  To my knowledge , it has never worked.

Because ICMP is not enabled on the firewall at the final hop. You do however get right to the subnet where the doamin is hosted and can even asume the next hop would be the one you are looking for,

I am told ICMP is intentionally disabled.

When I trace again today , there is a bad hop at nine , again .

Though , from a web browser , I can get to this site instantly.

What else might be the reason this is failing or lagging in mid-session  ?

Note , though I call this trace route a complete disaster , the tech I am trying to work with thinks its okay becuase the route "finally" resolves to the demarc.cogento.com

In my mind , it never resolves to what I told it to .

Any thoughts ?????

Every hop in the list is a handoff between ISP's. Hop #9 appears to be an XO router.
Routers are not required to respond to the icmp request. Apparently XO has setup their router not to respond. This has no affect on "real" traffic like web traffic getting through.
Traceroutes are good for basic troubleshooting, but don't really mean anything. Something like a long delay time at the router at hop 11 would indicate that XO potentially has an issue with the handoff with gogentco, but  there is nothing that you or your ISP can do about it, and probably something they are already aware of and working on to get fixed.
ICMP is often used as a denial of service attack vector and that is why many ISP routers have it disabled. Again, it has no affect on the actual data going through it.

okay then, but the lagging and dropping of the video call none the less exists and they want us to fix it....

SO ....... what do you think we can do to try and find a way to fix this  ???

just noticed you are with Teklinks.  I drive by there daily and am SUPER familiar with your competition about a block down the road.

I interviewed with those guys about 2 years ago and decided that 40K was too low to start.

Those 3 to 1 income ratios are way too agressive.

Unfortunately, this has nothing to do with your original post..
Your posted traceroutes don't show any delay at any one place.
You want video quality over the Internet??
You have to be very specific on what kind of internet feed  you have, what feed the remote end has, etc. you have not provided enough information to even begin forumating a theory.

>Those 3 to 1 income ratios are way too agressive.
I don't follow you on this one. You mean you interviewed with our competition? I don't work out of the BHAM office, so I didn't even know there was a competitor close by!
