I think that's what they are relieving...edge traffic volumes. If the local ISP cache box lowers it's maximum quality, the ISPs get relief.

The ISPs oversubscribed, and can't deal with this many people being at home all at once.






Citation needed. In the UK...

"UK broadband companies say they can cope with increased demand as many more people stay at home during the coronavirus crisis."

That's what they say now. Give them a few weeks and they'll start squealing. Every ISP oversubscribes for consumer segments. In the UK I guess not enough people are quarantined.

That has changed somewhat of late. With WBC there's no more "fixed" contention ratios and you pay for the last mile and then peer at national aggregation pops.

It's a far cry from the 50:1 IPStream product.


Some ISPs like Andrew & Arnolds don't oversubscribe, but they dont have unlimited plans either

It's not true to say that A&A don't oversubscribe. Instead the situation is that they're happy to buy more capacity to fulfil their offer, within reason.

If A&A subscribers could in theory move 10Tbps (if they all simultaneously did some sort of download from a hypothetical unlimited source) but in reality they never do and it peaks at something like 100Gbps, A&A are fulfilling their promise by ensuring they've got 100Gbps to do that.

Typically you'll never notice the difference, except on your bill, because if they had 100x more bandwidth upstream they'd pay a lot of money for that, even though it was unused and they'd have to pass that to you in the medium term.

However, the reality is a little closer to oversubscribing. Suppose A&A are paying for 10Gbps on a particular port somewhere, and at their busiest time of the week it typically runs at 9.8Gbps. Unfortunately the company selling it only wants to offer 100Gbps as the next step up, for five times the money. Another 10Gbps port isn't an option as there are no 10Gbps ports free. So A&A decides to sit on the problem, nobody is suffering at 9.8Gbps.

Next week it hits 10Gbps and seems likely it'd have gone to 11Gbps if that was possible. Oops. The firm they're buying that capacity from still has 100Gbps available, but they agree at last that they could add more 10Gbps ports, and will do so for the same price as the existing port. Unfortunately it means buying a new Cisco router, which Cisc says is on back order, it'll arrive in July.

Are A&A going to throw five times the money at the problem for this burst of maybe 30-40 minutes per week? Or are they going to tell you sorry but it'll be July and until then bandwidth at that peak across that particular link isn't what it ought to be? They're going to do the latter. Because at the end of the day it's a business. RevK is a good guy, but he's not looking to bankrupt the company to make some point.

A bit of that, and also probably a bit that their network needs and expectations, even when self-isolating, are lower than in the suburbs of tech-intensive Seattle.


Isn't this article about all of Europe though?

The very first line of the article

> Netflix will reduce the video quality on its service in Europe for the next 30 days, to reduce the strain on internet service providers.

emphasis mine.


A broadband company as referred to in the parent comment is an internet service provider.

1. This is EU-wide, just because one or two broadband companies in a specific country said so doesn't mean they all can handle it.

2. I have doubt that any broadband company would openly admit to not being able to handle the extra load.

Thank you! Found this entire thread very odd.


Just note, in your service contract the measure of whether service is working or not will likely be limited to being able to reach your ISPs website. As long as you can do that, it’s just the vagaries of the internet, other providers you know.

I think that's a porkie, I am with Vodafone (Openreach) and it's completely crippled.

Well if the companies say so

Wow, they SAY they can keep up, that proves nothing.

Log onto the internet at 1900hrs in central London on any normal day and be in for a shock
