mercutio

does tjng mean some location
nah looking at the mtr
to this person

meingtsla

tujunga canyon maybe

acf_

oh I see

meingtsla

which is basically still in the la metro area

[01:54]

acf_

ie, twc has backbone congestion...

[01:54]

mercutio

meingtsla: ahh
meingtsla: ok

[01:54]

acf_

on Verizon:

http://kremvax.acfsys.net/smokeping/images/Remote/verizon-snloca-dsl~ec2.acfsys.net_last_864000.png
both hops are in the same city (same building actually)
except (not visible on the smokeping) sometimes you get spikes up in the 2000ms range :/

[01:56]

mercutio

Acf: Like I saw. Interesting.
This is why I think smokeping is flawed :)

[01:59]

acf_

any idea where they might come from?
I think Verizon might have really big packet queues somewhere
because if you're downloading something, the latency shoots way up
so maybe if something on the connection creates bursts of network traffic periodicaly, it could cause the short 2000ms spikes

[02:00]

mercutio

ahh.
That sucks.
Is that on download as well as upload.
I wish I was in a position to fix all of these kinds of issues hah.

[02:03]

acf_

I can only recall download having issues, although I'm sure upload probably did too
I was thinking about doing a tunnel over it, and doing traffic shaping on that
to see if I can keep the Verizon queues mostly empty
but the latency sucks so bad anyway, it wasn't worth it imo

[02:04]

mercutio

Oh yip

[02:06]

interestnig.
so he's on socal.res.rr.com too

[02:09]

acf_

latency doesn't look bad to him though

[02:12]

mercutio

yeah but it's after midnight now isn't it?

[02:12]

acf_

ah yes

[02:12]

[02:19]

acf_

ok, just confirmed on my Verizon DSL line
currently downloading a file
latency is constant 1500ms
rather than 70ms otherwise

mercutio

wow
that's really annoying

acf_

yep

mercutio

do you have a static ip?

https://secure.dslreports.com/shownews/Listen-as-Comcast-Simply-Refuses-to-Let-You-Cancel-Service-129690

acf_

no, Verizon doesn't offer them

[02:22]

mercutio

damn

[02:22]

acf_

it also locks the DHCP lease to your MAC address
you have to unplug the modem and wait two hours, or call them to reset it

[02:22]

mercutio

screw that.

[02:25]

acf_

exactly. that's why everyone uses Comcast

[02:26]

mercutio

so i left this running and
worst ping of 26 seconds

[02:39]

acf_

wow. that's great

[02:39]

mercutio

worst ping to hop before of 6 seconds.
i wonder if that's an area thing
like something screws up quite close by

[02:39]

acf_

do you see it on multiple hops?
if it's DSL, it could be noise on the line

[02:40]

mercutio

do roadrunner do dsl?
only on last and second to last hop

[02:40]

acf_

hmm don't think so

[02:40]

mercutio

oh it was just bad again
and then 36 second
wow

acf_

just did the traffic shaping test

mercutio

and itw's 2 am or osmething isn't it

acf_

it worked
yeah, it's 2:41 am here

mercutio

cool.

[02:43]

acf_

looks like I can set the shaper up to around 2800kbit/s downstream

[02:49]

mercutio

cool.
Are you on VDSL?

acf_

and the latency stays at 35ms
no, ADSL+
ADSL2

mercutio

ok kilobits/sec
not killobytes/sec

acf_

yeah

mercutio

2.8 megabit isn't much
youhave what 3200 sync rate?

acf_

not sure

mercutio

So probably attenuation of ilke 50db.

acf_

I don't have access to the modem stats unfortunately

mercutio

oh that's strange.

acf_

I probably could, if I had a Windows box and downloaded Westell's software

mercutio

Sounds complicated.
And you can't just plug another modem in?
Because of the mac address crap.

acf_

yeah
I'll un plug this one tonight, so I can plug in the one with the integrated router thingy tomorrow
it's funny, I live like 1/4 mile from the CO, but Verizon isn't equipped with VDSL here so I can't have it

mercutio

you should be able to do much faster adsl speeds than that then.
i'm like 270 metres from cabinet.
so i suppsoe similar distance
Bearer: 0, Upstream rate = 1016 Kbps, Downstream rate = 23509 Kbps
and i sync at 23.5 megabit atm it seems down

[02:54]

acf_

looks like I'm on the "3.1 to 7 Mbps" plan
3.1Mbps my ass
I'll have to get those modem stats tomorrow when the MAC thing has reset
*later today

acf_ (and mercutio): Thing to remember about smokeping, and specifically those slaves is they're sitting on a connection shared by other servers. Backups, other users, etc all end up clogging the pipe :p It's why I have multiple slaves, not to show route health but the far-host health.
I will say however that my TWC connection is horribly congested.
A fact they refuse to acknowledge whatsoever

03:20:57 acf_ | currently downloading a file
03:21:06 acf_ | latency is constant 1500ms
^ this is why i use packet shaping

[07:44]

.... (idle for 17mn)

brycec

heh
packet shaping can help, but there's still an upstream issue that can't be completely worked-around
Same exact thing happens on my TWC connection

m0unds

eh, local latency shouldn't really get hammered too bad unless upstream is still on twc
but i've never heard a good thing about twc. my dad hated them so much he went with centurylink over them, and CL is horrible

[13:58]

brycec

m0unds: my headend node is saturated. there's no escaping it, for me anyways.
and I'm a fucking "business class" customer
but the SLA doesn't even guarantee in-network latency, just packet loss
(and hint: it's not guaranteeing 0 loss either)
Alas, the only alternative would be leased service (t1, fibre, whatever) and that's more than the budget will allow
technically, the current connection is over the budget too, but it's still the cheapest
Never been so assraped by an ISP
15/2 for $250/mo

m0unds

wow
well hey, if the comcast buyout works, you might be better off

acf_

just got off the phone with intelligent life at Verizon earlier today
I had complained about the congestion between the DSL node I'm on and their core

[16:16]

sga0_

Did you use that language?

[16:17]

***

sga0_ is now known as sga0

[16:17]

acf_

not exactly
but they seemed legitimately interested in doing something about it
and filed a ticket with whoever is responsible for the IP network part of it
it's kind of neat, since it's just a consumer DSL line
I don't even have an SLA or anything

[16:17]

sga0

Nice
I've had good service with Verizon
I'm on FIOS in Los Angeles

[16:19]

acf_

oh cool. I wish we had FIOS here
usually I call the consumer DSL support line
which I guess is a big mistake

[16:19]

sga0

You called business support?

[16:20]

acf_

I emailed them, and they called me back

[16:20]

sga0

I'm sorry, but it's ambigious - business or consumer support?

[16:22]

acf_

I'm not sure it was either, it was some guy at a Verizon office in New York
not like tech support or customer service or anything

[16:22]

sga0

Weird

[16:23]

acf_

teah
*yeah
brycec: have you tried calling various parts of TWC?
they might help you even if they don't have to?

[16:23]

brycec

have spoken with a couple parts
nope
and I don't have time
