The question is...how likely is Embarq to upgrade clearly oversold lines?

Considering I fought them for over 2 years with no luck, I highly doubt you will see a fix anytime in the near future! They have proven, time and time again, they really just do not care!

The question is, how well are they managing their circuits? Some do better at adding capacity as, needed, or even anticipated. Others seem to rely on reactive upgrades; wait until things break (or the users complain), then upgrade.

Probably a lot of it depends upon the financial health of the ISP.

...you only have a dedicated line for the few hundred feet back to the DSLAM. Once you reach the DSLAM...you are at the mercy of network congestion.

A lot of it has to do with how willing the company is to expand capacity. I was on a congested router with SBC a couple of years back. A post to the SBC Direct forum, here at DSLR, and they switched me to another aggregation router.

Of course, SBC had money to spare: They bought AT&T (then changed their name to, "AT&T").

My only fix was to go back to cable and now get these results during peak hours, and even faster during off peak.. and the best part... all for less $$$$ then I was paying for DSL!!

Also, it is not just naked DSL users either, as we had the full package deal from them and had so for like 7 years+!

So this is getting ridiculous. So much for using VOIP and naked DSL to get rid of the phone portion of my bill. Perhaps they punish users who opt for naked DSL by increasing the latency on the line ten fold.

:( level 3 having problems on both the east and west coast it seems

If you're referring to the packet loss on that graph, you're making it to the final hop with 0% packet loss.

That's how you can tell it's just routers throttling how much ICMP response traffic they'll generate; if it were true packet loss the percentage could never go down through the end of the trace. (ie, if you were dropping 53% of packets at hop14, then hops 15-17 would also need to show at least 53% packet loss as well)]]> http://www.dslreports.com/forum/remark,20754189 Mon, 07 Jul 2008 15:34:25 EDT Re: Random Spikes of Latency http://www.dslreports.com/forum/remark,20752998 anon : :( level 3 having problems on both the east and west coast it seems

the loss %'s in the 90s are false positives. they appear high to show the blockage of icmp ping 100% of the time. the 2.1% loss though, is where the problem is. sprintlink again proven to be the problem with 2.1% loss in routing change in addition to sporadic ping times as you can see from picture two in the maximum ping chart. packetloss+latency spikes up to 170ms=/voip/webcam chat/combo of both/, hell. forget trying to do anything with music as well, it will sync terrible no matter what you tune it to.]]> http://www.dslreports.com/forum/remark,20751458 Mon, 07 Jul 2008 00:28:11 EDT Re: Random Spikes of Latency http://www.dslreports.com/forum/remark,20750906 Hazy Arc : »/linequality/nil/2403911

You can see that once prime time hits, latency goes to hell. For the last couple years I've been running my VoIP traffic over DSL because it was more stable, but as of the last couple weeks I've moved that all over to my Comcast cable connection because VoIP is unusable on DSL at night with that kind of jitter.
