Re: East Tennessee latency problems
Yeah you may wanna also call in and say you are having an ongoing issue with network latency and that you would like to do a QCR test and forward the result to a tech. Hopefully they will figure out what you mean, QCR is the charter exe that just does a netstat and a bunch of other stuff and outputs it to the file. We are going through the same hops, look at my trace above, but my ms is decent.. So you may wanna just give them a ring since it does look like it occurs at a hop and not your router (they blame the router all the time), just a thought, I am going to wish for FiOS to come here tonight lol |

Maint should be done this week. I have not heard anything to the contrary.
I am not going to be doing this maint, actually, I will probably sleep through it. Our network engineer in Tri-Cities will be doing the actual cut over. He is one of the best within Charter.
Some of you have noticed that certain blocks have latency while others do not. Just depends on which circuit that particular block is going through.
Do have to reboot the router in Cleveland. Doing that Wed. night at around midnight. Should only be down for around half an hour. |

Kingsport went down from 2am - 8am Tues morn ISDN what was up? =) My ping to att is ok but still jumps 20ms just getting into the att hops, I would like 25ms pings to my game servers but alas just a dream |

| Ok.. Tuesday morning, our Network Engineer in Tri-Cities moved us to another ATT pipe..
More bandwidth and hopefully less latency..
Average latency is around 15-20 ms to Headend and between 30-50 ms accross the att network.. So you are looking at around 70 ms average. |

| what's the deal with at&T lately? several topics on here about at&t being the choke point. i don't recall my average ping being in the 70ms range a few months ago. seems to be a recent event and if the oc48 pipe doesn't take care of that then shouldn't it be time you guys look for another backbone provider? |

| Sadly I see no improvement. My ping times are still out-freaking-rageous. My game server is ping average is 173ms.
Yahoo ping is 166ms. Every server in 2142 is showing up amber or red, which are pretty much unplayable.

WTF is going on after the DHCP server in Kingsport? This is the problem I have been having for nearly a month.
Any one else in Kingsport seeing this? I appreciate the work Isdnwolf has done, but this is getting extremely annoying. |

I always have a great ping response at the dhcp server, but it's tat static one that is really kicking my ass. |

| If you are seeing >30ms latency to a host that is still within Charter's local network, then obviously that has nothing to do with their pipe to the internet. A local problem on your end, your node, something else with their local or fiber/coax network, or possibly you're saturating your bandwidth at the time of the test.

Look at my 4th hop. If my first 3 hops are well within normal then somehow magically after 7pm the 4th hop skyrockets by 100ms or more, then how can that be on my end?
I hit my DHCP server in this tracert at 10ms and under... when it leaves the DHCP server to the STATIC server it goes from 10ms up to 172ms.
6pm or earlier I have great ping times to servers. Around 9pm is when it's the worst.
If this was limited to one PC then I would think of it as a specific problem... but I just booted up my laptop and hit 3 open unsecure WiFi networks in my apartment complex and a house behind me and what do you know... all 3 WiFi networks are showing the EXACT same scenario. So the problem is not isolated to me or my modem when I am seeing it on 4 different networks.
Tracerts on the 3 WiFi connections as well as my own all choke out at static.kgpt.tn.com.
However it is odd that your time is much much better at static.kgpt.tn.com than mine and my neighbors. |

| I may have just tested it a bit early, I too see the 200ms+ times between those hops now.
That's not a "dhcp server" and "static server". Those are simply components of the reverse DNS names for those addresses. I'd also say they're not keeping that info all that up-to-date, the IP I have right now resolves as:
# host 24.159.42.xxx
xxx.42.159.24.in-addr.arpa domain name pointer 24-159-42-xxx.static.kgpt.tn.charter.com.
I don't have a static IP, power cycle the modem and I'll have a different one. Yet the IP I have right now has .static. in it's name. It would be nice if the *router* IPs they pipe traffic through had a reverse DNS name like oc48-att-atlanta.chartertn.net or something like that instead of a "cable modem" address, but they've probably got more important things to worry about...
So anyway, what's it look like the other way around, a trace from outside back towards my cable modem IP?

It's hard to be certain not knowing more about their network topology but I'm going to guess this IP is the handoff point between Charter and AT&T. If so then they're still saturated, OC48 or not. Again though, it's hard to be certain peering in from the outside. Perhaps ISDNWOLF or others can give some insight to the network layout here.
Oh, and here's some info on the "DHCP server" on Charter's local network and a few other things... Gotten from serial port off the cable modem during acquisition.
Cable Modem IP Address = 10.164.5.xx
Cable Modem Subnet Mask = 255.255.192.0
Relay Agent IP Address = 10.164.0.1
TimeOffset = -18000
Time Server IP Address #1 = 68.114.38.197
Gateway IP Address #1 = 10.164.0.1
TFTP Server IP Address = 68.114.38.197
DHCP Server IP Address = 68.114.38.194
TFTP boot filename = {something}
IP address lease time = 604770 seconds
IP address lease time remaining = 604768 seconds
DHCP state => Address acquisition successful
Adding IP address to Cable port successful !
Adding IP address to Ethernet port successful ! |

If this is only happening at night then you have been hit by the "oversold" bug. Nothing you can do but wait for them to add more bandwidth. 6-10pm is Internet prime time. If thats the only time its happening then they dont have enough bandwidth purchased. Hopefully it wont drag on for months like it did the last time. Around 2002/03 |

But around 8-9pm you can tack on 100-200 to the majority of those hops.
Thanks Wolfman for looking into it... been driving me nuts for over a month and I had such high hopes that the OC-48 would have taken care of that... but alas it continues on. |

Yeap, know those aren't DHCP and Static servers per-se. But it was easier to refer to them based on those names than typing out the IP or the full RDNS name.
I hate to say that I am glad you see the 200ms issue, but it is a relief that you do. I was baffled as to why you had a great response time at 'static' and mine was vastly higher than yours. Now it makes a lot more sense. |

I live in Dandridge Tennessee. Last two months have been bad. Not only slow ping rates but modem likes to reboot.
Charter came out a week ago and said every thing is fine (right) but they said it must be the modem. They replaced the modem and still doing the same.
Any word (wolf) on when they will get to the bottom of this??
PS--I have never doen a QCR test--can some one fill me in?

Well the attachment worked, not sure why the past did not.
Glad I stumbled upon this forum/thread. I see I am not alone in my misery!! |
