so it's finally the day we are going from gigabit fiber internet to 10
0:07
gigabit internet on our own
0:10
dedicated wavelength so behind this door
0:14
is my friends danny and chad from ital who are going to be helping me with this
0:20
little upgrade by the end of which we will have literally 10
0:25
times the bandwidth that we have currently to the main harbor exchange in
0:30
vancouver with glasswire you can instantly see
0:34
your current and past network activity detect malware and block badly behaving
0:38
apps on your pc or Android device use offer code Linus and get 25 off at the
0:43
link below
0:53
okay so step one uh collect underpants
0:57
step two we need to look at these two electrical
1:01
rooms this one is building a is that correct
1:04
and then we also need to take a look inside the electrical room of building f
1:07
because my understanding is that maybe you could help find it for me the main
1:12
fiber connection to telus is coming into
1:16
this building is that right yeah so here we found it this is the telus fiber
1:20
optic cable that is coming in from the street this is a it's a beefy it's a
1:25
beefy boy but you can actually see there's a reason for that
1:28
here we are so that right there is all
1:31
of the fiber strands that are protected not just by this orange and blue shea
1:36
thing but then also by this thick black sheathing around the outside so we can
1:41
tell three pairs so each one of these is a
1:45
send and receive pair but that doesn't necessarily mean that you can only have
1:49
three fiber optic connections running into this entire complex of business
1:54
units so one of the pairs here has actually been
1:59
there we go uh run into this guy so this is a cwdm and this takes a single 10
2:04
gigabit wavelength and then it is splitting it out into ten one gigabit
2:08
connections so our old connection actually runs off of this puppy right
2:13
here and then we just had two entire pairs that's what that would
2:17
be called dark fiber is that correct we're just not doing not doing anything
2:21
at all so now aha you can see here minus media group
2:26
gets its own so we're running off of three and four that are dedicated just
2:32
to us now we're gonna take ah there we go this right here and we're gonna plug
2:37
in the one that's sitting up on the top and instead of going into our gigabit
2:42
gear it's now gonna go into our 10 gig gear
2:45
now you guys said this was some kind of switch what was the brand of it
2:49
so what this sienna switch does is it allows itel to constantly monitor the
2:54
speed that we're getting make sure that nothing's going down there's no hiccups
2:57
or anything like that and then it's basically just going to pass through
3:01
over to building f where it will then carry over to our server room so to isp
3:07
or data center guys who work with this kind of stuff all the time i might as well be making a video about a
3:11
screwdriver i suppose but for those of you who don't i want to take this
3:15
opportunity because we're not ready to cut over to this yet we've got to make
3:20
sure that the transceiver on the other end in our server room matches this one
3:24
before we can go ahead and just pop the fibers in i wanted to show you
3:28
guys exactly what kind of gear we're looking at so this is a long-haul 10
3:33
gigabit transceiver so our fibers go in here
3:37
and then they are converted to copper signals that your computer or your
3:41
router or your switch in this case can understand and there's all kinds of
3:46
different types of these things everything from
3:50
10 kilometer long range to 40 kilometer long range to short range ones to ones
3:55
that are designed to carry a single wavelength the ones that are designed to
3:58
carry multiple wavelengths and the main difference for this one is that it's
4:02
going to be laser rather than led which is what you'd
4:05
normally use for just like one of the cheaper ones you get off ebay just you
4:09
know running from your server room to your you know editing room or whatever
4:13
else and the strength of the signal so
4:16
it's super bright because it's designed to go over very long distances you want
4:21
to make sure they're not mismatched because even if you have two long range ones if you've got a very long range one
4:26
and it's too bright for the distance of the cable you can actually get
4:29
attenuation so it's all dark magic to me but it's
4:33
pretty freaking cool okay so now we're headed over to the
4:36
electrical room of our building where honestly nothing really happens other
4:42
than that it's just like spliced together basically is that right
4:45
yeah okay so this is a good opportunity though to explain the difference between
4:50
having your own dedicated wavelength and having your own
4:54
dedicated fiber run so even though that fiber that's over in
4:58
building a is going to go all the way out to the road and to tell us his
5:02
nearest like like what would what would that be called
5:06
a splice point it's going to be combined with other pairs over there and it's
5:12
only that light wavelength that is actually dedicated to us along that path
5:17
and that path is dynamic like if if someone's you know digging a post and
5:22
cut something or whatever it's going to get automatically routed around but it's
5:26
still pretty much a direct path
5:30
tens of kilometers away to harbor center
5:33
and what we're expecting to see is somewhere in the neighborhood of 10
5:37
gigabit per second and about one millisecond of latency so you guys
5:42
actually had one of your texts did i overhear someone ran a benchmark and
5:46
what are we looking at from your switch
5:49
9.8 gig well where's my other point too
5:53
you bastards i can explain where it is yeah can you can you okay all right you
5:58
want to explain it no not on camera you don't want to explain it on camera all
6:01
right all right some something about tcp testing this is the thing about internet
6:04
service providers you know there's always an excuse there's no oh there's overhead overhead
6:10
okay so now we're over in our building so
6:13
building a was the first one of this complex so that's where everything comes
6:17
in from the street that makes sense so we've got one black
6:20
cable here we go that comes all the way up here
6:24
and then into what would this be like a splicer box
6:28
like what would you call this sure i'm calling it a splicer box but he's
6:32
splicing cabinet maybe it's detecting around and it doesn't matter anyway so
6:35
you can see here all our fiber strands are
6:39
separated here and this would normally be closed for protection and then it's
6:43
going right there we're the only ones in this building with fiber internet
6:46
obviously and then our yellow one goes into this orange sheath and then all the
6:51
way back down here to unit 102 so 101 102 103 and 104 are
6:59
all Linus media group but that's where our server room is so now we're gonna go
7:04
over there so now we're in our server room where that orange uh sheath that we saw in the
7:09
other building comes in from the top and then it comes in the back of our cabinet
7:13
and plugs into this guy just a patch panel okay cool so then we're actually
7:18
going to continue to use this exactly the same way we used to is that right
7:22
now the one extra piece of equipment that we had before that we will no
7:27
longer need actually is this mrv right here which was essentially a media
7:32
converter so we were taking this fiber out of our fiber patch panel and then we
7:37
reconfigured this guy so that we could run this copper connection into our
7:42
pfsense router which is actually over on
7:45
the back of our rack so this just goes away and i i get a you back
7:52
yes good fantastic so then danny
7:56
basically what you need to check is if these are
8:01
long-haul transceivers or short-range ones is that right not these not these
8:07
we need to check your new transceiver to make sure it's 10 gig my new transceiver
8:11
which one's that in your pf sense 10 gig
8:14
yeah it's just an sfp plus port so there's no transceiver okay then we'll
8:18
give you a transient yay okay so i've got up the menu and i think
8:23
i know which ones they are i think it's igb0 or one
8:26
i don't know which though so we're just it's gonna be a little bit of trial and
8:29
error here um so next step then is
8:32
message everyone and tell them the internet's going down
8:37
internet going down warning
8:43
and five four three
8:47
two one so i tell tells me normally this is a
8:51
two-person operation so you can just like both move them at the same time but
8:56
um we wanted to film it we only had one camera person available so i guess
9:00
everyone gets to sit inside in the dark of no internet they're both doing things
9:04
look danny's plugging in the other one so there we go so what have you moved
9:08
over all i did was plug the cable in okay so that old one gig hardware is
9:14
technically all still there the one gig circuit's still up in parallel we know
9:18
it works then we tear it down then we tear it down got it so now theoretically
9:23
over on the other end we're 10 gig okay
9:28
so theoretically i should see like some kind of led indicator on that
9:32
if it's working i guess right nothing so far so there's six rj45s
9:38
and two sfp plus right the smp plus are
9:42
not showing up in this place okay
9:45
so worst case scenario there is a pci x
9:48
pci express expansion slot on this thing and we definitely have sfp plus cards
9:53
that was definitely showing ixl 2 and 3 before though i'm sure
9:58
did they just die
10:02
what is this it doesn't actually say what it's trying to find
10:06
arp requests cannot find matching address what is that even five reboot
10:11
the system yeah let's reboot normally so while it was booting up ix2 and
10:16
three showed as all the devices were initializing
10:21
so uh they exist
10:24
they're just not showing up in the list i think the problem might be
10:29
that for lan interface i entered ixl0 instead of ixl0.1
10:34
shouldn't matter well
10:39
it's still freaking out about that 10.20.0.74 nonsense i'm rebooting on the
10:45
bright side we have a link now that's good thank you danny let's thanks
10:50
danny no pillow there's no update
10:54
holy crap i think it actually kept the
10:57
configuration from last time look at this
11:00
when is ixl3 it has an ip
11:04
okay so when interface
11:07
um you guys want to have a look at this it appears to be up
11:12
okay so we're not sure exactly what happened but the latest update is that
11:16
uh itels guys are seeing our Mac Address
11:20
what is that Anthony
11:24
why did you have those why were those aggregated i don't know
11:29
on our internet's up
11:32
legs
11:36
got leg killed today so
11:39
let the record show i actually did know what i was doing i
11:43
just didn't know that someone had tampered with my i mean sort of knew what i was doing
11:47
like i i could have checked this before they got here what was happening was two
11:52
of our eight interfaces just weren't showing up in this list because
11:57
there was a link aggregation group set up that was showing up but we didn't
12:02
recognize because we were looking for ixl3
12:05
so everything that i thought was supposed to happen with everyone arguing
12:09
with me where i was like no no blah blah blah it'll show up and all this stuff
12:15
and blah blah blah blah blah the only thing i did wrong was i bunged up
12:19
plugging in the fiber so that it wasn't lighting up since
12:22
then it's been i mean there's a there's
12:25
an element of user error you know what i'm sure all the network admins in there
12:29
the ones that aren't telling us that pfsense is totally unsuitable for 10 gig
12:33
are are telling me why i'm wrong but anyway the point is
12:36
you know what
12:39
bam it's working all right so what we want to do now is
12:43
ping our gateway and see if we're getting the advertised one millisecond
12:48
uh ping times so you're at percent here danny fifty percent part of that
12:53
response from your road oh yeah oh you're blaming my router now oh i see
12:57
how it's gonna be so we can actually see here whether we should blame my uh my
13:02
router or not it looks like our
13:05
send time is point three milliseconds
13:08
and then our round trip time is right in the neighborhood of two milliseconds
13:11
there so we can see that by refreshing it here it's really consistent
13:15
dang so it's all working we've got internet
13:18
but one of the coolest things about our sub two millisecond round trip time to
13:23
harbor center is that we could basically
13:26
have direct layer two access to
13:30
anything else that's in there so if we wanted to connect directly to a cdn or
13:35
if we wanted to put our own servers in there i mean i guess that's probably
13:38
expensive but theoretically we could do it right we just have a 10 gigabit pipe to harbor
13:44
center that happens to be bringing us internet now the way you explain it to
13:49
me we basically have five and a half gigabit to the broader internet but 10
13:54
gigabit to anything that's at vanix is
13:58
that right or harbor center it's your wavelength
14:02
okay five gigs of internet five and a half
14:07
six six with overhead sure
14:12
so all that's left now is to run a speed test
14:16
but we have a slight problem we're going to press go and we're going to discover
14:21
that speed test relies on the server at the other end
14:27
having the amount of bandwidth that you are testing for
14:31
so we just maxed out
14:34
someone's gigabit server somewhere because the reality of it is
14:39
if anyone had a multi-thousand dollar a month internet connection a 10 gig
14:44
connection they'd be using it for something it's not just sitting there
14:48
waiting for me to speed test i mean apparently it's got more down than it
14:51
does up which is fascinating but uh poor
14:54
urban fibers like what are you guys doing to me right now
14:58
so now what how do we test this thing what even do danny
15:04
multiple sources i mean you know what
15:09
oh a torrent a torrent could work well i wouldn't
15:12
know anything about torrenting danny you know what
15:16
i'm gonna call two and a half gig up okay for now and i'm just gonna do like
15:21
a fun test okay because technically google is in harbor center right so why
15:26
don't we upload something so slight correction google is peered there but
15:30
either way we should be looking at some pretty serious speeds here 2.6 gigs
15:36
let's upload it to youtube week week youtube you're weak all right we're
15:41
gonna have to find something else like what can we what can we like
15:45
hit with this
15:48
iperf test yeah i need that running on the thing
15:52
remotely so basically there's nothing that we can do to test this
15:56
other than hand this connection over to the Floatplane guys
15:59
and give them a server here in our server room and then do like
16:03
a live stream or something so maybe that's something that we'll do in the near future and see how hard we can hit
16:08
this thing in the meantime though massive thanks to danny and the itel
16:12
folks chad coming out here and helping us hook this up massive thanks for the
16:17
discount i guess it wasn't that substantial still very expensive but
16:21
they claim they're not making any money on it so you know
16:25
you know it's the word of an isp so they're pretty nice guys but
16:29
yeah i don't know and a massive shout out to our sponsor for today's video
16:34

17:19
disliked this video you can hit that button if you liked it hit like get subscribed or maybe consider checking
17:23
out where to buy the stuff we featured at the link in the video description i'm actually serious about that ital has
17:28
been absolutely fantastic to us i just love giving them a hard time um
17:32
they're they're only really business you guys don't do any consumer at this point do you
17:36
so there you go but at any rate they've been really good to us
17:40
and also while you're down there you can check out our merch store which has cool
17:43
shirts like this one and our community forum which is definitely worth a join
17:48
so we could actually host the forum out of here now there would be no reason not
17:51
to do that anymore fascinating we probably have to get a better ups
17:57
maybe like a generator back up okay not yet later
