	mkb has joined #arpnetworks	[05:13]
mkb	anyone else have ipv6 problems?	[05:14]
mhoran	Yeah all sorts of problems since Friday. I think they're still getting things settled into the new cage.	[05:17]
mkb	yeah I figured it was that	[05:19]
..... (idle for 24mn)
mhoran	Yeah, my IPv6 seems to be down completely. Looks like since 5:15am UTC.	[05:43]
...... (idle for 28mn)
	I sent a support ticket. IPv4 also seems to be quite laggy and my alerting keeps going off.	[06:12]

vom	ever since yesterday my VPS has had broken ipv6 - i can't ping my def. gw from it and inbound traces die one hop prior anyone else experiencing this ? should i open a ticket ?	[07:57]
	hmm - interesting - i had the unicast gw in my config for years (::1) - and it was working - but i just did a tcpdump and i see RA's with a LL so i removed the static gateway and rebooted - and now I have my def. gw via RA and all is well dunno if this is a known issue / related to the maintenance or what	[08:03]
............ (idle for 55mn)
***	tmarble has quit IRC (Remote host closed the connection)	[08:58]
mhoran	Ah interesting. I opened a ticket because I encountered the same. Something must have changed	[09:01]
***	anisfarhana has joined #arpnetworks	[09:03]
anisfarhana	Hello guys :D Are we having an issue with ipv6 connection right now?	[09:03]
mike-burns	anisfarhana: http://irclogger.arpnetworks.com/irclogger_log/arpnetworks?date=2019-04-21,Sun&sel=5#l1 - seems like it.	[09:05]
anisfarhana	What a relief. At least i know the problem is from arpnetworks.	[09:06]
mike-burns	Haha yeah -- it's not (necessarily) that you broke a config!	[09:06]
anisfarhana	I already sent support ticket too just now. mike-burns: This is first time i had problem with ipv6! But i am expecting there will be a problem with ipv6 due to maintenance.	[09:07]
mhoran	Maybe up_the_irons did this purposefully to get everyone back on IRC. Yeah oddly v6 was working fine after the migration but broke around 05:11 UTC.	[09:07]
anisfarhana	mhoran: I'm always here! :P Pity up_the_irons.	[09:08]
mhoran	Ha. I can't really tell because I hide joins and parts	[09:09]
anisfarhana	He must be busy right now inside the new cage.	[09:09]
mike-burns	Despite all our rage he is still just an admin in a cage.	[09:11]
anisfarhana	I can handover my force to him :P Use the force, Gary! :D	[09:12]
	So we don't have any ETA right now for this issue right?	[09:23]
***	ziyourenxiang__ has quit IRC (Ping timeout: 246 seconds)	[09:23]
anisfarhana	my ipv6 connections still okey on Friday though.	[09:25]
....... (idle for 30mn)
	I got replied from support team already :D Thanks arpnetwoks!	[09:55]
........... (idle for 52mn)
	Okey i got my ipv6 back :)	[10:47]
............. (idle for 1h4mn)
mhoran	Same! anisfarhana: do you have native ipv6 at home? Or using a tunnel?	[11:51]
anisfarhana	I disabled ipv6 at home. v4 to v6 :D	[11:52]

***	brycec has quit IRC (Ping timeout: 250 seconds)	[14:05]
	brycec has joined #arpnetworks	[14:18]
brycec	Alright, now _I'M_ having IPv6 issues >:( mtr from my VPS to google.com http://pastebitch.com/PVDS	[14:24]
mercutio	brycec: looking into it	[14:26]
brycec	thx	[14:26]
mercutio	can you ping fe80::1 ?	[14:26]
brycec	Yes mercutio Some really erratic trip times: 0, 5, 20, 0, 50 etc (ms)	[14:27]
mercutio	it's cisco	[14:27]
brycec	k, didn't know if it might be indicative of network load [too]	[14:28]
anisfarhana	I thought ipv6 is resolved now.	[14:28]
brycec	Oh and for reference, from my home (tunneled) to my Thunder http://pastebitch.com/EHZb	[14:28]
mercutio	oh hmm i have a diffrent subnet for you	[14:29]
brycec	hm?	[14:30]
mercutio	a650 that hop say a6c0	[14:30]
brycec	Ah, yeah I'm a650 No idea about that hop shrug	[14:31]
mercutio	that's really odd	[14:31]
brycec	::/0 fe80::1 UG 1024 3463630290 eth0 My default route remains fe80::1 so... shrugging harder	[14:31]
***	acf_ has quit IRC (Remote host closed the connection)	[14:32]
mercutio	yeh it might not know what to pick	[14:32]
brycec	Maybe my VLAN is misconfigured with the switch/router? (I'm more or less guessing, so I'll just shutup and let you do your thing)	[14:32]
mercutio	i moved you to the cisco earlier, but i tested and it was fine and now it's not! so not sure what's up with that	[14:33]
brycec	Computers were such a mistake :P	[14:33]
mercutio	i traced to ::3 fine before i can mtr to it now better brycec ?	[14:33]
brycec	Something changed... 1 sec It does seem to be working, yes. Though a6c0 still shows in traceroutes	[14:37]
mercutio	hmm i wonder if it's possible to change that because that's confusing :)	[14:38]
brycec	Personally, I don't think I care because I never see it, so long as things work :P	[14:38]
mercutio	heh yeh it doesn't happen with non routed subnets	[14:39]
brycec	Me and my /48 are "special" eh	[14:40]
mercutio	there's quite a few special ones	[14:40]
brycec	Well FWIW I appreciate having a /48, I'm using 0.0061% of it!	[14:41]
mercutio	heh i don't have ipv6 at home still	[14:41]
brycec	(by subnet, not address allocation)	[14:41]
mercutio	i tested from arp, and your subnet was accessible from arp still	[14:41]
anisfarhana	mercutio: oh really? how come?	[14:42]
mercutio	isp doesn't support it anisfarhana	[14:42]
anisfarhana	Interesting!	[14:43]
mercutio	ipv6 isn't very common here	[14:43]
anisfarhana	Change your ISP :D	[14:43]
brycec	(Or get a tunnel, yadda yadda. Not really the point, or important, at this juncture though.)	[14:43]
anisfarhana	I have options here for my ADSL, ipv4 only or with ipv6	[14:43]
mercutio	i don't actually have anywhere local to get tunnel from	[14:43]
brycec	Thank you so much for the speedy assist, mercutio ! And best of luck with the ongoing migrations.	[14:43]
mercutio	otherwise i probably would brycec: yeh sorry about that	[14:43]
anisfarhana	up_the_irons just fixed my ipv6 too :) anisfarhana is happy customer!	[14:44]
brycec	Sydney isn't "local" to you? :O /s	[14:44]
mercutio	so yeh you both are on cisco termination for ipv6 rather than openbsd now brycec: not really, it is further from the US than here so it will increase latency for all US traffic by about 35 msec or so and 135 vs 170 msec is actually quite noticably different	[14:44]
brycec	I imagine you could go through Hong Kong and have a decent trans-pacific latency.	[14:45]
mercutio	my friend visited china when he was living in england. latency was terrible between the two you'd think that china could have decent latency to england, but all the paths go via the US	[14:46]
brycec	No, I wouldn't think that at all. There's a whole goddamn continent between China and Europe, EITHER WAY YOU GO :P	[14:46]
mercutio	true	[14:47]
brycec	And I suspect the connections crossing the US are better than whatever crosses Russia and friends.	[14:47]
mercutio	europe is pretty good for connectivty, same with russia places like bulgaria are really cheap for high speed connections	[14:48]
brycec	The US has good economic factors for making good connections across the country. I don't imagine Russia has the same factors. But this is just conjecture on my part.	[14:48]
mercutio	the US has terrible pricing for internet for home users there are a few monopolies which hardly compete like comcast is like $80 USD for 100 megabit or something isn't it? on a dated cable network	[14:49]
brycec	You don't have to tell me :P	[14:50]
anisfarhana	Come here mercutio	[14:50]
mercutio	yeh so places like bulgaria are like $10 USD/month for internet	[14:50]
brycec	TIL there's undersea cable directly between New Zealand and the US, much to my surprise.	[14:50]
anisfarhana	You can enjoy my ipv6 here :D	[14:50]
mercutio	running fibre is mostly about labour...	[14:51]
brycec	(well, direct to Hawaii, then from Hawaii to mainland US making landfall in Silicon Valley)	[14:51]
mercutio	yeh there's more than one cable they introduced a new higher latency one but it still keeps the pricing better it's 125ish msec from auckland to los angeles then latency to auckland, and to your pop	[14:51]
brycec	Yep I just read about that one (the third such, went live last June)	[14:53]
mercutio	our latency to singapore is similar but bandwidth to singapore tends to be much worse	[14:53]
brycec	Still disppointing that 15,000km only gets you 125ms	[14:54]
mercutio	yeh it's hard to do more direct paths 110 msec or something would be noticably faster it's still reasonably direct gpon has a bit more latency than i'd like too	[14:54]
brycec	Quite surprising how many submarine cables come ashore just 100km from where I live	[14:56]
mercutio	it's like 0.6 to 1.4 msec or something like variable i think our cable lands between san jose and los angeles so it ends up being transported to one or the other	[14:56]
brycec	Hawaiki (the newest one) is the one that lands near me https://www.youtube.com/watch?v=5F_aWegm_ok video of the boat arriving, apparently	[14:58]
BryceBot	YouTube video: "Pacific City Cable Landing" by Hawaiki Cable	[15:00]
brycec	Oh including the cable actually coming out of some sort of ground conduit, this is neat	[15:01]
mercutio	oh their latency to Oregon is pretty good, 126msec it says heh they offer transport to one wilshire it's so much easier to terminate at a popular location it makes it much easier to sell wavelengths to smaller companies	[15:02]
brycec	I've studied the video, matched it up to aerial photography, and subsequently realized I've driven past its landing station several times without ever realizing it was there. (Tucked back from the road, nondescript, etc) So that was a good use of my Sunday afternoon	[15:12]
***	ksthomas has joined #arpnetworks	[15:17]
brycec	"The fiber optic cable may be buried at less than one meter, but not less than three feet, in hard ground such as portions of the "reef area" along the cable route." Lol, that's a window of about 3.5in/9cm	[15:20]
mercutio	haha remember google abandoned a city becuase they were laying fibre too shallow?	[15:21]
brycec	I hadn't heard that	[15:22]
mercutio	https://www.bizjournals.com/atlanta/news/2019/02/11/google-fiber-to-make-its-first-market-exit-in.html	[15:23]
brycec	It figures there would be someone else who'd already done what I was doing The fiber optic cable may be buried at less than one meter, but not less than three feet, in hard ground such as portions of the "reef area" along the cable route. derp, wrong clipboard https://cryptome.org/eyeball/cablew/cablew-eyeball.htm	[15:23]
mercutio	they lay my fibre in my neighbours garden it seems a stupid place to put cables to my mind	[15:24]
brycec	Better than in YOUR garden :P	[15:25]
mercutio	well it's more likely to have a spade through it new zealand is doing pretty well with fibre though	[15:25]
brycec	Fiber bear me is all in underground service ducts and the like, fortunately. But there are areas with it strung pole-to-pole too, both out of the way at least. *Fibre near	[15:26]
mercutio	like there is affordable 1000/500 megabit fibre connections now in most of the country, from multiple providers there will only be one provider to get the actual bit to your house but head ends are reasonably affordable too, so it makes it more accessible for ilke say a backup provider to start up and have their own fibre links	[15:26]
brycec	Good for y'all!	[15:27]
mercutio	that said most people will only have one provider yeh it sounded kind of iffy at first, with 100/50 and 30/10 plans standardised by the government	[15:27]
brycec	Agh I'm reading through this marine website's report of the laying of a cable and they keep using "nm" for nautical miles and it's really infuriating me. ("NM" is the proper abbreviation for nautical miles, AND YOU'RE A DAMN MARINE WEBSITE WHY DON'T YOU KNOW THIS)	[15:28]
mercutio	but the fibre providers came out with faster plans and now 100/20 is pretty much teh default for a decentish price	[15:28]
brycec	Nothing wrong with 100/50 (or even 30/10) those are very serviceable connections for Most People (TM)	[15:28]
mercutio	it's like $45 for 100/20 and $55 for 1000/500 or something for residential for wholesale cost though	[15:29]
brycec	Meanwhile, I've got 100/100 and life is fanatstic and everythign is backed-up In The Cloud!	[15:29]
BryceBot	TO THE CLOUD!!!	[15:29]
mercutio	NZD which is about 0.7x USD	[15:29]
brycec	@exch 55 NZD USD	[15:29]
BryceBot	55 NZD -> 36.763206847849 USD (as of Sun, 21 Apr 2019 15:00:00 -0700)	[15:29]
mercutio	well 100/20 is a lot better than 30/10 as a base offering so yeah it's affordable enough that providers can put a little markup on it and buy transit etc base plans are moe like $80 or $90 i think @exch 80 nzd usd	[15:30]
BryceBot	80 NZD -> 53.473755415053 USD (as of Sun, 21 Apr 2019 15:00:00 -0700)	[15:31]
brycec	"These patrols continued until the cable was completely buried in the fishing grounds. Little fishing activity occurred in the area during the cable installation, and no conflicts occurred. One humpback whale was observed in the vicinity during post-lay burial." I appreciate the "one whale was seen" note in their report lol	[15:31]
mercutio	there's a cable from perth to singapore ish and it gets hit all the time https://en.wikipedia.org/wiki/SEA-ME-WE_3	[15:32]
BryceBot	SEA-ME-WE 3 :: SEA-ME-WE3 or South-East Asia - Middle East - Western Europe 3 is an optical submarine telecommunications cable linking those regions and is the longest in the world. Completed in late 2000, it is led by France Telecom and China Telecom, and is administered by Singtel, a telecommunications operator owned by the Government of Singapore. The Consortium is formed by 92 other investors from the telecom industry. It was commissioned...	[15:32]
mercutio	i think it's around singapore somewhere it gets hit, but it goes all over the place hah it has two fibre pairs with 2.3 terabit/sec per pair you know that cable should give better china to england latency if it was used :) i suppose it's still pretty indirect	[15:33]
brycec	Reading reports from circa-2000 and they're describing cables with 560Mbps/pair and like wow we've come a long, long way in a short time.	[15:35]
mercutio	yeah	[15:36]
mkb	you ever read that neil stephenson article for wired?	[15:36]
brycec	Also, 283kb file for a nav chart "Note: These images are large, and will take several minutes to load."	[15:37]
mercutio	hahaha	[15:37]
mkb	http://archive.wired.com/wired/archive/4.12/ffglass_pr.html	[15:37]
mercutio	2000 is when things were rapidly taking off though	[15:37]
brycec	I think I sneeze slower than it took to load.	[15:37]
mercutio	in 2011 i had like 16 megabit adsl now i have 1000/500 fibre 16/1 adsl in 2002 i had like 256kbit/128kbit cable in 2001 i still had dialup at home :)	[15:37]
brycec	Ditto, that's right around the time I went from dial-up (MPPP, two phone lines baby!) to cable (10/1 I think)	[15:39]
mercutio	you jumped straight to 10 megabit?	[15:39]
brycec	May not have even been that fast, it was a long time ago!	[15:39]
mercutio	i had faster net at work in 2001 at least i never could web browse on dialup comfortably coming from bbs's even ssh was laggy on dialup	[15:40]
brycec	I remember it was a white Motorola SurfBoard modem... and I remember having all kinds of fun fiddling with it and the HFC network (before ISPs actually started to care about "security")	[15:41]
mercutio	64kbit isdn was a lot lower latency	[15:41]
brycec	Yeah, I remember relying greatly upon a caching proxy	[15:41]
mercutio	heh i've actually found browsing has got slower over time but i think it's the browsers... like i had an old version of chromium somewhere stored and i loaded it and it was stupidly fast	[15:41]
brycec	mkb: Interesting (albeit LONG! Over 40k words) read, thanks (Typically, that works out to 80+ pages in book form!)	[15:44]
mercutio	wow sri lanka had a huge bomb killed more than 200 people	[15:46]
brycec	Oh you mean actual explosion, Shit. (Thought "a huge bomb" like a failed cable, tech boom crash, etc)	[15:46]

acf_	hmm so my arp metal box just rebooted after roughly 2 years of uptime > Physical move of ARP Metal™ servers to new cage I'm guessing that was this?	[17:14]
mhoran	Yup.	[17:17]
acf_	is everything still in wilshire annex, just a different cage?	[17:21]
mhoran	Not sure, but I think so.	[17:22]
mercutio	different cage, different floor	[17:27]
.......... (idle for 45mn)
***	vom has quit IRC (Quit: leaving)	[18:12]
........ (idle for 37mn)
mnathani	Does traffic trombone the SMF link between the cages? Ie: external request comes in and terminates on the old floor /cage then travels via smf to new cage to the VPS / Thunder End point and back over the SMF to the old cage and back out the transit link the request initially came in on? or does each cage have its own Transit / Peering connections as well	[18:49]
***	qbit has joined #arpnetworks	[18:59]
mercutio	some traffic traverses we're advertising prefixes on both sides atm and some people are still terminated in the old cage	[19:13]
....... (idle for 33mn)
mnathani	Is the MTU on the 1gig SMF run 1500 or more like 9/10,000 Jumbo frame? I assume its an 802.1Q Trunk link carrying multiple VLANs?	[19:46]
mercutio	nah it doesn't tunnel vlans, it just has tagged vlan pass trhough so 1500 per valn so 1500 through to vlan i should say it's when you want vlan inside vlan inside vlan etc you need larger mtu, and even then people usually run 1600 or such rather than 9k unless they want larger mtu for traffic.. but high mtu isn't very popular still basically large mtu is more useful on higher bandwidth links but then the mtu overhead isn't that big a concern, and there's lots of hardware offload now days..	[19:47]
acf_	I'm guessing the plan is to eventually move everything to your "new" cage	[19:54]
mercutio	yeah	[19:54]
..... (idle for 20mn)
mnathani	thanks mercutio!	[20:14]
............................. (idle for 2h24mn)
acf_	who are the transit providers we have now? last I remember it was NTT and level3, but it seems things have changed right now everything seems to be routed through "atlanticmetro"	[22:38]
