brycecwtf... is this even a valid rDNS? monitor.instavps.net.104.36.199.in-addr.arpa
199.36.104.84 is the IP that resolves to it
[12:34]
mkblooks to me like somebody forgot the . at the end of the PTR entry [12:35]
brycecheh
brycec is trying to debug why a customer on their network is getting horrible download speeds from his service
Full speed from ARP and another datacenter (IO Networks, Phoenix). But shit speed from my home Comcast, from Hostdime in Orlando, FL, and from a datacenter in North Carolina
brycec is collecting mtr's, whee
[12:37]
mercutiobrycec: it'll be some peering dispute probbably. [12:53]
brycecheh
And I *just* closed the doc with all the mtr's so I can't speak too smartly on it
But there was one node in the route (in sjc) that was common to most bottlenecks. And also all transit from gtt.
[12:54]
mercutiothere were like 3 cables cut in california the other day too [12:55]
brycec(not all bottlenecks had sjc, but all routes through sjc were bottlenecked) [12:55]
mercutiothe sabotage thing [12:55]
brycecyeah. crazy vandalism [12:56]
mercutioit sounds like it's most likely malicious
rather than vandalism
[12:56]
brycecI consider vandalism malicious,.. [12:56]
mercutioahh i think of vandalism like drunk kids smashing letter boxes [12:56]
brycecAnd that isn't malicious? [12:56]
mercutiostill malicious, but not nearly as premeditated.. [12:57]
brycec@ud malicious [12:57]
BryceBotmalicious: Malicious is another word for bad. Usually used to describe a virus. See also:rmenacing <2006-02-27T00:00:00+00:00> Example: "WITH:r1#: heyr2#: hir1#: have u downloaded 'pwnage free website maker'?r2#: no thats got malicious code in it!rWITHOUT:r1#: heyr2#: hir1# have u downloaded 'pwnage free website maker'?r2#: no thats got a virus!" [12:57]
bryceclol [12:57]
mercutiowhereas sabotage is much more on purpose [12:57]
brycecsabotage is directed
vandalism is just malicious for the sake of being malicious
at least, that's my definition
[13:01]
mercutioyeh
that's how i see it too
but it's been called vandalism in news a bit
[13:05]
mike-burnsFor the lulz. [13:07]
mercutioyou think? [13:12]
mike-burnsmike-burns shrugs [13:12]
brycecbrycec thinks. about things. and stuff. [13:13]
mercutioheh
have you tried tcptrace btw brycec .. you were saying about performance issues to some locations..
[13:13]
brycectechnically "from" [13:14]
mercutioand sometimes it's hard to do testing between dodgy location and dodgy location.
err from a dodgy location..
no ... the dodgy location is in between
coffee, work!
[13:14]
brycecI got it down to 3 hops, from their equipment to their datacenter's speedtest, it was dog slow. [13:14]
mercutioso you can tcpdump and run traceroute on it [13:15]
brycecSo I closed that as "the provider is throttling you, not my problem" [13:15]
mercutioahh [13:15]

brycec6
yay
"vandalism" http://arstechnica.com/tech-policy/2015/07/california-fiber-optic-cable-vandalism-continues-unabated/
[13:53]
BryceBotArs Technica: "California fiber optic cable vandalism continues unabated" [13:56]
brycec"...the bureau has discovered "no real motive" for the cable cutting." [13:57]
mercutiothat doesn't mean there's no motive [13:57]
brycecJust that they haven't been able to piece one together, I know. [13:58]
mercutioit just seems like they're underplaying it [13:58]
m0undslots of telecom vandalism like that is perpetrated by former employees [13:58]
mercutioi was reading a while back about how the US doesn't want to increase taxes on gas. [13:58]
brycecIf The World understood how fragile everything was, they would (or should be) panicking non-stop. [13:58]
mercutioand they've got no money to repair bridges, etc.
and they've been trying to find money with no luck
but the gas tax hasn't increased even to keep in line with inflation, as the voters don't want to pay more
[13:59]
m0undsa big part of the issue w/that is that gov agencies don't want their budgets cut [13:59]
mercutioand no-one wants to become unpopular... [13:59]
mike-burnsIt's the gray aliens cutting the cables. [14:00]
m0undsmike-burns: you're not supposed to talk about Them [14:00]
brycecm0unds: I see that as one of the biggest issues overall. Nobody ever wants their budget cut, even if they don't need it. So at the end of the year they burn through whatever leftover budget they have so it's not cut next year, and might even be increased. [14:00]
mike-burnsOh shi [14:00]
brycecDecember was always a good month for telecom equipment sales ;P [14:00]
m0undsbrycec: yep, having worked for tribal gov i got to see that on a smaller scale every single year
it was awful
[14:01]
brycecNow if those greedy fuckers would quit that, we could start making some progress on this debt
brycec rages
[14:01]
m0undsevery november, buy stupid shit we don't want or need so we can deplete our budget. if we don't, they might cut it [14:01]
mercutiobut i think usually we're meant to have no idea how much work goes into power, water, roads, internet etc [14:01]
m0undsthen they stopped asking me to find stupid stuff to buy and transferred it to travel and sent people to vegas for no reason and our budget got cut :) [14:01]
mercutiom0unds: damn. [14:02]
bryceclol m0unds [14:02]
mercutiom0unds: i don't think that's uncommon though [14:02]
m0undsit's not at all [14:02]
mercutioi've heard of people who have no budget for stationery etc too [14:02]
m0undswe had to beg for stuff like canned air
or printer paper
[14:02]
mercutioso it can go both ways..
oh, so they had money left in their budget because they wouldn't let you buy anything?
[14:02]
m0undsbecause they wouldn't let me order stuff like that w/our money because they always felt it was the division's budget who should cover office supplies
they wouldn't let me buy equipment, so we ran really lean w/spares and stuff
they'd let me buy non capex stuff like tools or whatever
[14:03]
mercutiopeoples attitudes towards things like office supplies is a good way to judge how well things are functioning i reckon [14:04]
m0undsbut no switch gear or spare disks or anything like that [14:04]
mercutiobecause it's a small cost overall really, and it shows willingness or not whether to allow things through in a timely manner
m0unds: a server is a tool right? :)
[14:04]
brycecso is this "external hdd" [14:05]
m0undsnah, it was based more on $ amount [14:06]
brycecOh, so not all tools either then [14:06]
m0undsno, they let me buy anything that was a tool [14:06]
bryceceg: $150 lineman's set vs $150 external hdd [14:06]
m0undsit was stupid
vs
$50 SSD

yeah
i couldn't buy spare ssds
but i could buy retarded things like..cable analyzers
$1800
so backwards, that place
it seems the tribal casinos who have a corporation running their business enterprises tend to do somewhat better in managing money
like, organizationally speaking
[14:06]
mercutioheh [14:09]
m0undsupdated osx on my mbp and it seems that disk access is significantly slower now for some reason [14:10]
mercutiossd or hdd?
maybe ssd needs a refresh
[14:18]
m0undsssd
i'll probably do it w/the next osx release
just tested it and it benchmarked within spec. meh.
[14:19]
mercutiomaybe it's some sync thing [14:27]
m0undscould be, don't know
boot was horribly slow and it was terribly slow to open a disk image to install the doxie client
one really nice thing about it being hot is that even with my AC set conservatively, it feels downright amazing to come back indoors
[14:37]
...... (idle for 26mn)
mercutioheh, i kind of feel that way about having heater on inside and going outside
come back in and it's much warmer than when you left..
[15:04]
m0undsyeah
just had a sweet microburst w/thunderstorm
75+ mph winds for 2 mins or so

m0undshaha, great. lost about 1/3 of the northern facing part of my roof to that thunderstorm, lol
peeled it right off and threw it in my front yard
[16:23]
...... (idle for 26mn)
brycecoh shit that really sucks [16:50]
m0undsyeah, i went out front to make sure i didn't have tree damage and there was a pile of shingles
seems like it only really impacted people w/2-story houses. there's a couple houses up the road from me who had new roofs installed in the last 2 yrs who have more extensive damage than me
no fun at all
[16:51]
about to get another round - would have loved to go up and place a tarp up there, but there's too much lightning atm [16:59]
brycecOoh fun
And good luck
[17:00]

mercutiom0unds: do you often get short thunderstorms like that?
sounds insane :)
no time to prepare and all
[23:36]
m0undsdesert thunderstorms are usually like that [23:36]
mercutioahh [23:37]
m0undshit really hard, dump tons of rain really fast, cause flooding [23:37]
mercutioi've seen rapid rain before, but it's usually quite light but a lot of it
so just a bit of surface flooding rather than damage
[23:37]
brycec@wiki flash flood [23:38]
BryceBotFlash flood :: A flash flood is a rapid flooding of geomorphic low-lying areas: washes, rivers, dry lakes and basins. It may be caused by heavy rain associated with a severe thunderstorm, hurricane, tropical storm, or meltwater from ice or snow flowing over ice sheets or snowfields. Flash floods may occur after the collapse of a natural ice or debris dam, or a human structure such as... http://en.wikipedia.org/wiki/Flash%20flood [23:38]
m0unds^ [23:38]
brycec^^ what m0unds lives with, and what I grew up with
fun stuff
[23:38]
m0undsevery afternoon during monsoon season = flash flood watches or warnings [23:38]
mercutioit was the wind rather than the rain that was damaging though, right? [23:39]
m0undsright [23:39]
mercutiothe motorways here don't have good water clearance
it's bloody annoying
so whenever there's a lot of rain quickly, there's a lot of water lying on the road, and people drive too fast
and trucks tend to spray it up
[23:39]
m0undsit's enough of an issue in my county that there's a flood control authority whose only duty is to handle what they call arroyos
sort of like big-ass canals that channel flood waters into the rio grande
[23:39]
mercutiowhat country are you in? [23:40]
m0undscounty - bernalillo county, new mexico, usa [23:40]
mercutioi saw pictures of the tidal wave in japan after the earthquake a few years back
that was insane
oh and thailand had insane flooding
ahh,..
i kind of thought the US was mostly pretty dry
and that flooding/flash storms etc were more likely in islandish countries
[23:40]
brycecHere's a pic from a couple years back, mercutio http://watchdog.org/wp-content/blogs.dir/1/files/2013/09/flash-flooding-krqe.png [23:41]
mercutiouhh
that looks menacing
[23:41]
m0undsyeah, that's hitting a bridge pylon along interstate 40 [23:41]
mercutiois that some kind of river thing normally [23:41]
m0undssan mateo bridge
no
it's dry
hahaha
[23:42]
mercutiook [23:42]
m0undsit's a flood control canal [23:42]
mercutiothe other side is dry
ahh ok
[23:42]
m0undswhen it rains, they fill with water [23:42]
mercutioi see
very dirty water..
[23:42]
m0undsyeah, it's a desert [23:42]
brycec(Matching news story http://watchdog.org/105990/after-a-long-drought-rain-pounds-new-mexico/) [23:42]

m0undsthat's the canal in the photo [23:43]
mercutiotwo years of drought wow
so the ground is all hard
and can't absorb water?
[23:43]
m0undsright [23:44]
brycecyep, because dry [23:44]
m0undshttp://www.amafca.org/media/floodphotos/TruckinNDC.jpg [23:44]
mercutiosheit [23:44]
brycecCould be worse, m0unds http://i.azcentral.com/i/b/c/4/L169_CIFRcdeda899cabeb2cb13ea2734d82bc4cb.jpg [23:44]
mercutioi dunno if i'd rather be in or out of the truck [23:44]
m0undswhoops [23:45]
mercutioi imagine in is probably a "little" safer [23:45]
brycec(http://archive.azcentral.com/community/phoenix/free/20130915phoenix-man-new-mexico-flooding.html ) [23:45]
m0undsouch
poor elephant butte
[23:45]
brycecto be fair, that was T or C, NM ;P [23:45]
mercutio10 inches of rain, wow
1" is bad enough for me :/
[23:46]
m0undsyeah, that was the summer that our transformers at work flooded and blew up a bunch of my gear
haha
[23:46]
bryceclol the pie chart at the bottom http://www.srh.noaa.gov/abq/?n=prepawaremonsoonflashfloods
(I lol because it's stupd but true)
[23:46]
m0undslol
ahahahah
the "drove car into water"
omg
[23:47]
BryceBotThat's what she said!! [23:47]
brycecI remember the news reiterating that point so. many. times. do NOT. It is usually deeper than you think, etc [23:47]
mercutioyeh [23:48]
brycecAnd drove into water --> swept away in vehicle very eassily. [23:48]
mercutiousually people walk first [23:48]

BryceBotYouTube video: "North Diversion Channel August 13, 2014 - AFD Deployment" by Albuquerque Metro Arroyo Flood Control Authority [23:48]
mercutioif they're trying to get into their home or something
and people mark it
if driving through, you follow someone else
[23:48]
m0undstimelapse shows how fast it fills [23:48]
mercutiodon't try to shfit around people etc. [23:48]
brycecYeah no kidding m0unds. All of a sudden a wall rushing in [23:49]
m0undsyeah, it's wacky - most of the flood control stuff in the city dumps into that particular channel
it empties into the river in northern abq
[23:49]
mercutiolook how few are from structural failure
that's what i'd worry about haha
but your'e more likely to just get flooding coming into your house
and lose electricity and not be able to get stuff dry
and have everything go mouldy
the cleanup must suck
i'm on a hill, i dunno what i'm worried about :)
[23:49]
m0undsyeah, the people who are dumb and build on a floodplain end up with their house filling with mud [23:51]
brycecThe hill giving way?
mercutio: I'll point out that the temps are usually 35C+ so it's AC lost too. "and lose electricity and not be able to get stuff dry"
[23:51]
mercutiooh
so it's humid too
and sticky
[23:53]
BryceBotThat's what she said!! [23:53]
mercutioyeah i think erosion here is unlikely [23:53]
brycecYeah. Real gross without AC, and life-threatening. [23:54]
mercutiothat said, the drains at the bottom of my driveway are all screwed
they're taking ages trying to fix them
i couldn't use my driveway the other day
i'd just be stuck at home :/
do they have ads on tv saying to not drive into the water?
when there were earthquakes in my old city the roads got heaps of holes in them, and people kept driving
by rivers was extra dangerous.
because often near rivers you've got underground rivers too...
[23:54]
brycecYes indeed, probably. (I seem to recall there were, but it's been quite a number of years since I watched TV commercials.) [23:58]
