Na, dial back the length so they can churn more out faster at an ever increasing price.
The same way humans do. A mistake outside of their control happens and they get trapped.
The cheap brand of something they know is crap. Say they are into water colour painting, get them the cheapest set you can find on Amazon, but not so cheap that it looks like a kids gift.
It's all made up on the spot?

1 gig gpon is different to 1 gig direct access so it depends how the service is delivered.
But honestly changing from a 1Gb wan to 5gb or 10gb is a significant change in price especially if you need to use ppp.
I would stick with 1Gb.

The day the boss figures out why I hate apple schools so much.
These stories are originally posted over the past decade on Reddits TalesfromTechSupport so I am copying over to Lemmy to help bring some life into this /c/
---------------------------------------------------
Some of you know I work for an ISP in a land down under. This incident took place a few months years ago when Apple ios 7.1 came out
-----------------------------------------------------
Just got back from lunch one day and one of our layer 2 wholesalers call up to log a "fault"
>Me: G'day slazer speaking >ResellerIT: Hi mate, I am wanting to log a speed fault with one of our private schools. >Me: no worries mate. What school? >ResellerIT: RegionalPrivateSchool. Your favourite one, they are only getting really high latency and between 5 to 10mb/s
damn it not those guys again
Back story. When this school went live their hardware firewall had a bug where after x amount of data was pushed, it could only do about 20mb/s in either direction.
>Me: Considering previous problems with that school have they rebooted their firewall? >ResellerIT: Yes, odd thing happened though, when the firewall came up it ran at the 100mb/s for about 10 - 15 min before dropping back again. >Me: Odd, let me check it out.
I log onto the radio and see the school usage is bouncing between 80 to 100mb/s.
>Me: Mate, have you looked at their current usage? >ResellerIT: No, why would I? >Me: Just look. You will work it out. >ResellerIT: Bugger me, that's quite a but of usage. I'll take it from here, sorry to call you mate.
/call
I kept the radio screen open in the background in case he called back and went back to my "active internet monitoring" AKA Reddit while listening to LRRLive on Twitch.
A few hours later I get an email from my boss asking what is happening at RegionalPrivateSchool, he got a call from the account manager. The only time the account manager gets involved is when he isn't getting in info out of his IT team (ResellerIT).
I flicked him an email back recapping my chat with ResellerIT and look at the radio it is still flatlining 80mb/s both ways.
I decided to take a look as to why a school with no students in it is still using 80% of their bandwidth in both directions. So I run the SuperSecretSexySpecial command on the radio that shows the top 20 source and destination IPs along with packets per second in real time.
When looking at the SuperSecretSexySpecial output I do some reverse look ups on the addresses. The school seemed to be pulling an arse tone of traffic from the local Akamai cache and pushing just as much up to addresses that map back to dsl services.
I start thinking, why is the school doing so much data? First thought, second Wednesday of the month Windows updates. But then I thought surely a school should run WSUS in case a bad patch comes out. As for the upload maybe some of the staff have discovered torrents aren't blocked on the firewall and let them run overnight.
I shoot my findings though to my boss, the account manager and ResellerIT. I include in the email that this is all speculation as well as some pointers for fixing it they can pass onto the schools IT guys. I get an email back from the account manager with some comments from the schools IT people saying they don't run windows, it is an Apple school and they are already running the apple version of WSUS. They also boasted that their school was one of the ipad trial schools. 1,300 students all with ipads, my second worse nightmare.
Then I remembered what my work iphone did this morning and an article I was reading at lunch, ios 7.1 for iphone, ipad and ipod came out a few days ago and we all know what happens next. The flood of app updates.
I decided to call the school and talk with their IT guys about running some tests for me. First step was to remove the apple update server network cable. When he did, the traffic dropped back from 80mb/s both ways to about 15mb/s. I asked them to plug the server back in and surely when it came back online the usage started again.
At that point I speculated that the student devices are calling back to the school to get the ios7.1 update and any apps that also require updates.
-----------------------------------------------------------------------------
The following Friday I get an email from the account manager, thanking me for helping with the issue at the school. It turns out I was spot on with the student devices calling back to the school for app updates. After the schools IT guy reconfigured the apple server their speed tests were back up to 100mb/s both ways and sub 15ms response times.
The boss was so happy with my work he let me off early on Friday with a bottle of something special.

Do rotating plates in microwaves help when heating food?
Microwaves tend to come in 2 types, ones with a rotating plate and ones without. Assuming everything else is equal about a microwave does rotating the food assist with the reheating?
Over engineering a radio link can cause problems too.
Another tale from the the land downunder. This time for all you RF geeks. I apologise in advance if I use dB, dBm, and dBi incorrectly, I tend to use them interchangeably at work.
----------------------------------------------------
One of those random things I have to do is support wireless gear that our ISP sells on the side to system integrators for point to point wireless between buildings. It is fairly easy work, we over engineer the links to perform better than the system integrators expect. This is a story about how the original engineer over engineered the link too much. The link was installed about 6 years ago and from what I understand hasn't performed as expected.
---------------------------------------------------
In the office, at my desk working on how one of our transit providers fudged up their route map and was advertising our address space back to us, a story for another time maybe.
phone rings
>Me: G'day slazer speaking. >Customer: Hi, its Customer from [redacted], we bought a wireless link from your firm few years ago and it has been working mostly well till last week when it fell over and we haven't been able to get it back. >Me: Ooooookk, let me grab your details and I will give it a crack. >Customer: The box in the rack says Redline AN50E and the link light is off. >Me: all right, do you still have management access to the radio? >Customer: I do on this side, not the remote site obviously. >Me: Makes sense. on the status page what are the RSSI and SNR values >Customer: RSSI says -86 dbm for all 3 values and SNR is 0 dBm >Me: Is the other end powered on? >Customer: Yes, the guys in the other office can login to the management as well. >Me: That's good, can they tell you the values on that side too?
hold music starts
>Customer: They are seeing the same values.
damn
>Me: Do you mind if we come down and have a look? >Customer: No worries mate, just ask for me at reception.
I make a list of kit we will need for the job and "delegate" it to my minion to load into the van and we head out.
---------------------------------------------------
We get to site and Customer shows us around the master end of the link. I spot the first of many problems. The ethernet is running in half duplex mode (may account for their poor performance.) and the radio is running at 20dB transmit power.
I turn to Customer.
>Me: have you played with any of these settings? >Customer: When it was originally installed the tech said if we have any problems with the link we should turn the transmit power up to 20.
I stare blankly at him for a few seconds before double checking I'm not going insane. I make note of the usual misconfiguration suspects, frequency, channel size, encryption enabled, correct encryption key and drop the transmit power down to 1 dB. We head over to the slave end. Most of the settings are correct, with the exception of transmit power, again it is running at 20dB. I drop it back to 1dB and see the SNR come up above zero for a few seconds before disappearing.
We do a test on the indoor coax cable going to the roof and see no RF coming back down the cable. Damn a faulty outdoor unit. So we head up to the roof and see what we can do about the outdoor unit.
I let my minion and Customer go up the ladder first and as I pop my head out of the roof access hole I see a disaster.
The original tech installed a 60cm panel for a rf link which is no more than 50M. Rf geeks will know why this is a disaster. 20dB of transmit power along with a 28dBi antenna, no way that is legal in Australia.
We swap out the outdoor unit on the slave site, because we were on that side, and as soon as we plugged in the new outdoor unit it started chirping away with its alignment buzzer saying it has the maximum modulation.
>Me: That's not good. >Minion: What do you mean? The link is working with this new outdoor unit, so we found the faulty part. >Me: Yea, but where is the antenna connected at the moment? >Minion: In the faulty unit. >Me: Yes, so with 1 dB transmit power on both end and only one 30cm panel on the master side we are forming a link. >Minion: So? >Me: What do you think will happen when we attach the 60 cm panel and put the transmit power back to 20dB? >Minion: It will get saturated and the link will fail. >Me: Yes, so all the drop outs they are talking about is because the link was overengineered too much.
We reattached the panel and looked at the management RSSI -36dB, SNR 30dB.
>Me: That has sorted it.
phone rings, Customer comes up on caller ID
>Me: Hi mate, we got it back up, how is it looking? >Customer: The link light is on, but I cant ping across the link.
damn it Rf is up and talking but no traffic is passing, the encryption key must be wrong. I get him to correct the encryption key and his traffic starts flowing again.
I confirm the modulation and transmit power are ok and head back over to the master end to talk with Customer.
---------------------------------------------
>Me: The outdoor unit is most likely to have burnt out because the RF levels were too strong. >Customer: I notice now when I put the transmit power to 20dB the link goes offline. >Me: Never change that value to above 1 ever >Customer: Ok then. The speeds are better, before it was running between 6 and 12 Mb/s now it is saying 54Mb/s >Me: Yes, because of RF magic we turned the signal power down to get a better signal. >Customer: I'll accept that.
And with that done, Minion and I went back to the office.

Context for those who aren't in the RF world. Imagine having a conversation with someone across an alleyway with one person shouting at the top of their lungs and the other using a megaphone. At some point hearing damage kicks in.
The time we interfered with a national mobile carrier.
When using new wireless kit, never assume the vendor knows what they are doing, most of the time they do not know what the local laws regarding wireless equipment even are. We have some vendors ignore standards while others follow the standard so closely the kit becomes unusable.
------------------------------------------------------------------------------------------------------------
We installed a new 900Mhz radio to a customer who was in a particular bad spot. All seem well, the customer was getting the speed over the wireless and the latency was rather good.
A few weeks after install I get a call from the customer.
ring ring
>Me: G'day slazer speaking. >Cus: Hi, this is [manager] calling from [customer] we have a guy here saying the radio on our roof is interfering with [national mobile carrier] in the area. >Me: Ooook, that doesn't sound good. Can I talk with him? >Cus: Sure. I'll shoot the call down to reception where he is.
call transfer
>Me: G'day this is Slazer, we run the kit on the roof, what is the issue? >CarrierTech: This is CarrierTech from [contracting firm] we have been sent out by [national carrier] to find out why their customers are experiencing call problems in this area. >Me: I see, is [Cus] still hanging around? >CarrierTech: Yes, >Me: Sweet, I need to have a quick word with him and we can sort this out.
Phone passed back to Cus
>Me: Hi mate, Thanks for calling us. We will handle everything from here and you wont have to do anything. >Cus: Ok, sounds good, I will pass you back to CarrierTech
Phone ping pong finishes.
>Me: Right mate, lets get this sorted. What are you seeing and how can we resolve it. >CarrierTech: I noticed the radio on this roof and our kit is saying it is running in the 900Mhz band. What brand and model is the radio? >Me: It is a Ubiquiti Nanobridge M900. >CarrierTech: Is the firmware up to date and you are running in the Australian country code? >Me: Yes. >CarrierTech: Ok, so it looks like it currently isn't complying with Aussie rules because it is sitting in the middle of the 900Mhz band assigned to [national carrier]. >Me: Not good, What is there band? >CarrierTech: [freq band] >Me: Yea, we are sitting in the middle of that, luckily this is a backup link so I can mess with it during business hours. Let me lock out those frequencies and reboot the unit.
few min later
>Me: Ok, I have gone as far away as I can from their band, how is it looking? >CarrierTech: I will have to check from outside. Can I have a number I can call you back on? >Me: sure, [insert company number] >CarrierTech: OK, I will call back a little later.
-------------------------------------------------------------------------------------------------------
About 20 min later he calls back.
>CarrierTech: It looks like that has cleared up the problem. Where does this link go back to? >Me: [insert address from city 10Km away] >CarrierTech: sigh I spent the entire day there yesterday chasing down the same problem and narrowed it down to that street. I should of started at this end. >Me: Well, my apologies mate, I will have to get in touch with the vendor and get this fixed for the next firmware release. >CarrierTech: Yes. I am sure [National Carrier] will also push them and the ACMA about it. >Me: On that note. I assume because the problem is fixed we won't be getting a call from them? >CarrierTech: No, if they complained to the ACMA it would be 6 months before they could do anything about it. >Me: Sounds about right for a government department, just out of curiously how many sites were affected by this? >CarrierTech: About 20 to 30 sites. >Me: wow, now I am really glad you called us first.
insert ending formalities
/End call
--------------------------------------------------------------------------------------------------------
I let the boss know what happened and he was glad how it worked out.
Last time we had a run in with the ACMA it ended badly for them, but that is another tale for another time.
