100Gbps today is like 300 customers. Hmmmmmm

I think my ISP would treat that as a million customers.

More like 15,000 if you average 1TB per customer per month with 50%-ish burst.

Retail consumers do not receive dedicated bandwidth. ISPs will oversubscribe the promised amount 25x-100x because not everyone is using it at peak capacity 24x7.

Residential customers don’t use anything close to maximum bandwidth regularly. It gets better as you with faster connections and more users. At 100Mbps you can roughly do 20:1 over subscription, bump that to 1Gbps and 50:1 generally works fine. StarLink is aiming for roughly 50-100Mbps connections so this likely represents around 20,000 to 40,000 customers per 100Gbps link. “SpaceX - Starlink (AS14593) has added 2x100G bringing their capacity to a total of 2x2x100G. They are connected to the route servers.” In other words they hit 40,000 to 80,000 customers and are preparing for another 40,000 to 80,000.

  Note that it's hard to quantify this evenly between ISPs, because isp A might have a hundred gig port to an ix and meet all the major cdns and Netflix and Google (YouTube video traffic) over the ix exclusively, while ISP B might have also a hundred gig port but also set up many PNIs for direct cross connect and peering with the largest cdns and sources of traffic. Meaning that ISP B will need to upgrade its ix port at a much later date relative to subscriber count, but its PNIs and cross connects are opaque and hard to know about from a public/external third party perspective.

  That is customer that are currently being covered. It is 40k to 80k at both West Coast, Midwest and Northeast so that is Times 3 plus the rural area of the West and how many that is. Then we have Europe. So I feel like there is a lot of bandwidth for millions. I can't find the coverage per satellite. How much ground do they each cover?

  they announced they hit 145,000 customers, so that math doesn't add up. they will need roughly 50:1 to be anywhere near profitable.

    They don't transmit between satellites right now, and even if they did they'd still want to minimize that bandwidth and keep any transmissions that they can one hop. One station feeds about one state on average, and I doubt they're feeding everything through that one connection.

No, it's not, you can fit an absolute shitload of individual 1 gigabit per second symmetric last mile residential customers in the actual usage of a 100Gbps transit port, before it starts hitting 65Gbps in evening peaks and you start thinking of needing to upgrade.

  A metric shitload or an imperial shitload?
  - walrus01 5y ago
    Nautical shitload, obviously, it's measured by the fucktonne
  - dotancohen 5y ago
    An absolute shitload. That's a metric shitload plus 273.

Aside from oversubscription only a fraction of any customer's traffic will traverse the IX. The ratio will depend on who Starlink is peering with on the SIX (not necessarily everyone) and the traffic flows to/from those ASN's. That said there are some very significant content peers present on the SIX: Akamai, Amazon, Apple, Edgecast, Facebook, Google, Microsoft, Valve, among others. Hurricane Electric is also there and has an open peering policy despite being a very large ISP with a significant percentage of Internet routes and traffic.

  Starlink has BGP sessions with the SIX route servers so from that alone you know they peer broadly on the exchange.

I don't think this is for customers, they are using Google's network for customers. More likely it's for the Starlink building.

You really think your ISP reserves 300Mbit of their bandwidth just for you? I got curious and checked the local IX (smaller EU country), one of the largest ISPs has 4x100G connections, but their combined maximum ingress+egress almost never goes beyond 100G.

Read your contract for gigabit fiber. Here in France the ones i've read best promised 512Kb/s available bandwidth at any time, for consumer offers advertizing between 100/100 and 1000/250Mbit/s. Dedicated gigabit bandwidth is still in the thousands of euros monthly, or in the hundreds in optimal situation (if you're already in a well-connected colo).
