I had always thought that the hivemind opinion on the reasonably tech-versed parts of the internet was that Telus was running a reasonably modern network, and Shaw's was pieced together with coat hangers? I now of course can't find a single post anywhere to back that up.

Surely the lovely speeds in peak times has nothing to do with my local wiring though, right? Telus has been beating the "shared neighbourhood bandwidth" thing into my head for like 15 years now.

It's really a YMMV thing. Neither is the clear "most reliable/fastest home network in the lower mainland"

It's not the central office, but the lines going to your house. If they get damaged, water can get in when it rains and it affects the radio signal in the cable, and it can go back to working fine when it dries up. For above ground lines, a big issue is squirrels gnawing on lines, since they work really well for wearing down their teeth. Asking if it was raining was just to narrow down if it was a line issue outside or something else.

It's not really a matter of Shaw's or Telus' infrastructure being better than the other, as they're both pretty similar and one or the other may be better depending on what the upkeep is like in your area. A fiber line goes out to your neighbourhood and hits a node, where it gets to your residence using either coax or telephone wire, both of which have their own upsides and downsides. If you're in a Shaw or Telus neighbourhood that has fiber to the home/premise, it just skips that last step of converting to coax/twisted pair and terminates at the ONT in your home. Any damage to the wiring is going to cause issues, whether it's coax, twisted pair or fiber.

When I used to be tech support, I've had to set up maintenance calls for all sorts of issues as simple as trucks snagging lines to people not calling before they dig, to birds building nests on taps outside or bees making a hive out of a pedestal. The connection to the ISP still has to go from your house to the node/headend, and there's a lot along the way that can go wrong even if everything is set up perfectly.

The difference between coax and twisted pair is that coax can carry an order of magnitude more bandwidth, but you're sharing that bandwidth with everyone on the same part of the coax network as you up to where the line converts to fiber to the headend. With DSL, you have your own line to the DSLAM, but I believe a single run of twisted pair is limited to a relatively low amount (30-40Mbps?), and the quality of the connection is dependant on far away you are from the DSLAM (I work for Shaw so I'm more knowledgable on the cable part of things, so anyone feel free to correct me if I'm wrong about anything on the phone side).

As far as what causes saturation, I'll just copy a post I made earlier:

Coxswain Balls posted:

That sucks. I've seen way less saturated nodes in the past year due to the progress we've made with analog reclamation, but there's still a lot more that can be done to free up bandwidth to keep ahead of it recurring in the future.

Fiber/coax hybrid internet works with a fiber line going into your neighbourhood (Or node), then it switches to the coax lines that were originally used for TV; that coax part of the network is where the saturation comes in. A cable signal is split between different QAM channels, which were originally used for analog TV stations way back in the day. These QAM channels can be utilized much more effectively by switching over to digital TV (You can fit a handful of HD channels in the same QAM space a single SD analog channel takes up), or my using them for data (One QAM channel is analogous to 37Mbps of downstream throughput, and I think 27Mbps of upstream).

Your node has a specific amount of QAM channels set for downstream and upstream use, and that bandwidth has to be shared between everyone on the node. If your node has 24 channels set for downstream, that's 888Mbps available for use at any given time (37*24=888). If your node has 50 people on it, but 4 of those people have a 250Mbps connection and are downloading at full speed all at the same time, that 888Mbps is completely saturated for the period of time they're all simultaneously using the connection.

One of the solutions for this is getting more channels used for downstream and upstream through more efficient use of the signal. Right now in a lot of places channels are being broadcast three times, in analog, digital standard definition and digital high definition. Shaw's removed non-Basic, analog cable in most areas across the country and repurposed them for data, but there are still a few places where it's still around due to Reasons, and those are more often than not the places that are susceptible to saturation. Future upgrades would hopefully be getting rid of standard definition channels once everyone has high definition capable equipment, so only one feed of a channel is being carried on the signal.

The other solution is splitting a node by running a new fiber line into the neighbourhood. This splits those 50 people in the first example into two nodes of 25 people, and each new node will hopefully be able to handle the load.

The difficulties with the first option are the old holdouts who don't want to upgrade to digital TV, but that becomes less of an issue as time goes on. There's still tons of standard definition equipment out there, so I don't imagine that going away any time soon, however.

Problems with the second option are infrastructure related, as permits need to be acquired, trenches need to be run and agencies need to cooperate, so it can take a lot of time from start to finish. And if all four of those heavy users end up on the same node after the split, you're right back at square one.

Shaw's set to be getting rid of all analog cable in Vancouver in the near future, so that will hopefully improve things a lot there. Hybrid fiber-coax is still a pretty future-proof solution compared to fiber to the neighbourhood DSL, but that all depends on the ISP having a good handle on subscribers per node and efficient usage of the bandwidth cable has to offer. The vast, vast majority of the cable signal is being used for TV, but as more people cut the cord or upgrade their television equipment, more of that cable spectrum can be dedicated to internet, or at least getting rid of redundant analog/standard-definition channels.

If you PM me an address, I can look into it further for you when I get into work tomorrow. There isn't a customer-facing database available, since the node you're on often changes as upgrades are done to the infrastructure, but I can pull up usage reports to determine whether or not your current node is saturated. If the area utilization percentage isn't high, then barring any additional issues, you should be getting your rated speeds when wired directly to the modem and monitor inbound/outbound traffic directly from the NIC.

Yeah, that's true but you do get a discount for a new client... $20 or something..? Not like that would probably make a difference to you in your situation. You can probably pick up modem for a bit cheaper though if that helps.

Personally, I'm happy paying a premium to them just so I can tell Telus to gently caress off and screw their regressive practices.

Even then Telus doesn't care if you exceed the bandwith allocation. Or if you're in ETTH/FTTH they literally don't track your bandwidth usage.

My main reason is that I have TV and 50/10 from Telus. Teksavvy isn't (allowed?) to sell 50/10 yet, their max is 25 down. Even when I plan to ditch TV soon I'll stick with Telus because the 50/10 works out to about the same as Teksavvy's 25/5 after the dry loop fees etc.

In summary, the regulated rates Teksavvy has to pay to their last mile is too high for them to compete.

TV is an obvious reason and I certainly understand that. I cut the cord 4-5 years ago so it's meaningless to be but I understand.

The issue with Telus and their bandwidth though is they made it clear they have lowered caps and can enforce it if the deign to.... so who knows. Once they do start enforcing it all bets are off. And that attitude pisses me off.

I am nowhere near a cap, but I pay Teksavvy unlimited on principal more than anything.

Is that for a business account? People in FTTH areas are able to get gigabit fiber, which I've seen on the odd residential account for a bit over $100/month. It's not advertised anywhere, so I don't know what the process is for actually getting it other than calling in and asking for it, or if it's some limited offer while they test future feasibility. The only time I ever saw it was from people who wanted to try it out, but never used it to its full potential and downgraded to something cheaper.

Actually, I was mistaken and it was $1000/mo for 25/25, not 15/15. But they also wanted a $1000 installation fee.

Anyways, yes it was a business account and when I called in to ask about residential fibre they said no. Which residential regions are you seeing with FTTH?

In my experience, the places with residential FTTH are brand new housing developments or condos where there is no infrastructure to speak of, so why not run fiber while it's all being done and the trenches are open. They're usually in suburbs on the far reaches of the city, so the tradeoff in having awesome internet is your overpriced house by the city dump and an hour plus commute every day.

As far as cable upload goes, I definitely hear you and a lot of us on the technical side make a point of being vocal about it whenever a bunch of VPs come around to our office for their quarterly meetings. The current scuttlebutt is that executive bonuses this year are going to be tied to whether or not we improve our upload capability and percentage of saturated nodes, but I'm so far away from that side of the business that it could just be something to quiet us down. Something definitely needs to be done, because with stuff like twitch streaming and Shaw's acquisition of a cloud services company, the need for faster upload is only going to increase further.

One of the reasons why upload is usually so much lower than download (At least with cable) has to do with how the transmitting equipment at the ISP's headend is much more powerful and expensive than the transmitter in the $100 modem at your residence. Using a radio analogy (Which isn't too far off the mark, since that's what cable is), a broadcast tower is able to send a signal to your handheld receiver 100km away, but if you try to use your handheld device to transmit back to that base station 100km away, the signal isn't going to be anywhere near as clear.

Upload is really nice for things like game servers, sending HD video to people, or for doing online file backups. I want to give something like Crashplan a try, but things will take forever with my current 5Mbps upload.

I don't see how a mainstream user would want anything more than 1mbit up at this point. They just want to consume YouTube and Netflix.

I want faster up in order to do content creation like live streaming, have better access to my file server and workstation in my home when I'm remote.

I've heard this and that Upstream coming from people homes creates a ton of noise on the line if people have older cable wiring in their house or whatever on their lines. Upload also becomes saturated much quicker then download for reasons that were never explained to me, that's why ISPs will limited filesharing uploading, but not downloading. If DOCSIS 3.1 ever makes it to mainstream that would solve the majority of these issues.

I'm not quite sure the radio analogy is a good one. According to the principle of reciprocity, the base station should be able to pick up the handheld signal just as well as it can transmit to it.

With the cable plant, if you want to get technical, it's because docsis channel widths (in 1.0 and 1.1) upstream are half as wide as downstream channel widths, because they (rightly in my opinion) designed the format for an end user who's not going to use as much upload as they use down.

They've since made a 6.4Mhz channel width in docsis 3.0 (which is what shaw uses) but since Shaw tries to model the QAM channel allocation around the average user (Mantle for instance with a 1 mbit upstream) They will allocate a lot more downstream channels than upstream in any particular chassis.

Also, 1.0 mbits up is going to constrict downloads after a certain point because you do need some way to acknowledge your 500mbit downstream data flow.

As far as xdsl, I'm not sure why the difference in upload and download, but I can only assume that it's due to the scarcity of (reliable) frequency that they can pipe over a pair (or 2 pairs in the case of vdsl or whatever) of wires.
