Such a genius move, surprising nobody saw it coming. Just think: he will already have access to a large base of customer's roofs (which SolarCity effectively owns) --- 1 million by 2018. Then, it's just a hop, skip, and a jump to an on-demand, fully-cached, mesh network. They're probably not far from being able to provide internet service to all SolarCity customers, just a bit of a modification to the contract.

Free internet access for Tesla vehicles too, I imagine.

Tesla vehicles already come with free data! Built-in international roaming 4G SIM. Free data for first 4 years.

I suspect this is just a phase. I don't have any hard stats at the moment to back it up, so it's just a feeling. Internet culture is still very young. At least in the US based on the election last week, the majority of people 18-25 voted progressive in most states. These are people who have never known the world without internet access. I guess that the people who voted the other way are folks who have transitioned i…

> none of these are universally true of course

Er... yes, I basically deeply disagree with all of your points :-)

That still wouldn’t give you access to piracy sites, for which the FBI has required US ISPs to censor them from their DNS servers. I’ve had this occur quite a few times now that 8.8.8.8 (yes, verified with DNSSEC to be the real one) and DNS servers of US ISPs returned different IPs than the authoritative nameservers, and the returned IPs always showing a neat "The FBI has seized this property due to piracy" link.

You were probably witnessing normal DNS propagation after the authoritative name servers had been changed. Keep in mind that the nameserver data you see in "whois" may not be up to date. When a site is seized, law enforcement goes direct to the registry (GLTD operator, such as Verisign), not the registrar. See http://domainincite.com/2766-icann-had-no-role-in-seizing-to... for an example

For 2 years?

The authoritative nameservers still return the original IP, I can still access the site from anywhere in the world except the US.

napkin math (chemistry style): (4425 satellites * 23Gbps) / ((60,000PB of fixed internet traffic / 1 month [1]) * (12 months / 365 days) * (1 day / 24 hours ) * (1 hour / 60 minutes) * (1 minute / 60 seconds) * (8 bits / 1 byte) * (1024 Tera / 1 Peta) * (1024 Tera / 1 Giga)) = An astounding O(54% of global internet traffic) [2]! Obviously there are many many more variables in this [3]. Nonetheless this will be super…

More numbers to crunch:

- Satellite with LEO orbit covers 1-2 percent of earth surface with 10 degree elevation.

- Land occupies less than 30% of earth's surface area. Urban areas occupy less than 3 percent of the Earth's land surface. That's where the customers are.

You have to divide at least by 100.

no one saw it coming? they anounced this in 2015. Here is a video where elon explains the system very well in 2015. https://www.youtube.com/watch?v=AHeZHyOnsm4

People also speculated that this was the reason Alphabet invested in SpaceX. (Which was around the same time as that announcement)

Do you think that having workers/employees overwork, sometimes mindlessly; worrying about their jobs or otherwise go hungry - is a factor in the problem you described?

It definitely is. Plenty of evidence all around.

It’s not unheard of the FBI just storming into data centers, seizing entire racks, just because some of the systems in them might be connected to piracy sites.

> Can you give some examples?

I’m sorry, I know this will undermine the credibility of the statement, but I won’t link to content where linking to it can potentially be a crime on here. Sorry.

Something I find interesting about this: what does it mean for countries who monitor and filter/block content (think China)? Presumably since this isn't using their national infrastructure they would lose all control of it, no? I wonder how those countries would respond to SpaceX wanting to let their citizens use the service. Unless I'm missing something it seems to me like they wouldn't really be able to stop it.

They can always jam whatever bands it operates on. They can make it illegal to tx/rx in those bands.
