VPN use for a free and open Internet is abnormal - not a long term solution to issues like censorship.
They're already out of reach for normal users. Companies will offer better ways to block or detect usage for lucrative gov contracts. Simply making it illegal will detour most people.
I don't understand why VPN crackdown is thought to be impossible. ISPs have a good idea of what normal traffic looks like and a very good map of the Internet. The Internet may be big. To an ISP, is it really that big? Netflix, Google, YouTube, Dropbox etc are normal. Your companies VPN IP are normal.
That's unusual! Open connection to a DNS port? sending large amounts of data? its encrypted? No one has accessed that digital ocean IP before on this network! Lets throttle, interrupt it periodically or flag that user. Someone else sending large amounts data to a known VPN IP range? block, throttle, close connection, police knock on door etc.
policy change, not more VPNs.
This is why you and OP's comment are detracting and unproductive. We made this. We run the show.

"We've only been trying technological solutions for the past hundred years and look at what they've achieved. We've been trying political solutions for thousands of years."
Though, I agree that we need to be aware of the limitations we and our systems impose on technical solutions. That said, perhaps we should play to our strengths?
Holocaust, Nazi Science, Atomic bombs, Stalin's industrialization, mass surveillance, cold war? Man, 20-th century was such a mess, technology only made that mess more messy, and good stuff was achieved by political discussion, dialog, not because of new technologies (although technologies makes both dialog and murdering much easier)
We absolutely need policy change, but we also need to use and encourage tech that makes it impossible for bad policies to take these to gain a foothold.
Don't mean to be pedantic but I think you mean "deter". "Detour" = reroute, like "we're taking a detour to get some gas". "Deter" = Discourage, like "making something illegal deters law abiding citizens from doing it".
> I don't understand why VPN crackdown is thought to be impossible.
Because it's hard to distinguish VPN traffic from legitimate traffic and false positives will be extremely bad for the ISP.

In order: Many VPNs will use standard HTTPs ports rather than DNS. There are numerous reasons to send large amounts of data, like backups. Encryption is quickly becoming the default, major video sites like YouTube and Netflix are encrypted for instance. Software developers are likely to access DigitalOcean IP addresses.
I do believe that at ISP scale it's possible to identify VPNs though and the things you've mentioned could contribute to a heuristic algorithm. Some other things to add are the geographical diversity of the users accessing a server (legitimate video services will have PoPs near a user, so few will cross the country), the distribution of response times and sizes (a pure web server will have lots of small, ~100ms responses, a video server will have lots of infrequent very high bandwidth transfers) and if you can access it, the outgoing connections of the servers themselves (e.g. Cogent can tell that a server is generating user traffic rather than business traffic).
I don't think so. Chinese firewall can block VPN. For example, the easiest way to see if the user is using a VPN is to count a number of IP addresses they connect to.
> and false positives will be extremely bad for the ISP.
How exactly?
China is a special case as unlike most other countries, all major ISPs are state owned. When you own every internet connection in the country, it's much easier to spot VPNs.
When you're say Comcast, you only see the connections your customers make and accept, you can't see what VPN servers are doing.
> How exactly?
In countries other than China, where government control is less prevalent and the government is overtly democratic, false positives will result in anger in the populace, which will lead to the person implementing the policy losing power or at the very least, a degree of support.
It doesn't matter who owns the ISPs if the government has the power and will to force all of them to comply.
It was implemented in a matter of months and has improved over time from a simple DNS redirect to now blocking IP ranges and DPI.
Internet Censorship and ISP wide blocking to us westerners is a new thing and I think people here are speaking during a time where we have it pretty good.
There is no ISP proactive battle against VPNs. Yes, you may be able to get through your companies firewall but is that the same? VPN use in China is difficult and becoming more so.
UK ISPs are now logging DNS requests from order of the government. In the beginning the ISPs complained and said it was technologically difficult. I wouldn't be surprised if that was just a call to access some gov funds and hey presto both parties win.
That is until some government official learns about them.
That is not important. In Russia even private ISP are required to install a firewall to block access to sites that are spreading illegal information (and they are also required to install a device that is monitoring whether the blocking policies are followed). There is also a law that will oblige ISPs record and keep customers' traffic in the future.
> When you're say Comcast, you only see the connections your customers make and accept, you can't see what VPN servers are doing.
A user of VPN typically has a single outgoing connection to a data center IP and that is easy to detect for an ISP. There is no need to see the VPN server's connections if you see the user's ones.
> where government control is less prevalent and the government is overtly democratic, false positives will result in anger in the populace
In those countries there will be no censorship and no need for a VPN. Also, most people don't use tools like VPNs and use Internet mostly for sites like social networks. Even if there are 1% of annoyed customers that cannot use VPN or SSH, the rest 99% won't notice that.
Another few feet down that slippery slope.
Well it's not exactly a novel idea. China, North Korea, Iran, Iraq, Oman, Turkey and others have implemented bans or heavy restrictions for quite some time now.
I imagine it might be trickier for the US to implement such a plan vs. a country like Russia.
Second, this doesn't make any sense. How would you avoid rate limits by using a VPN?
The ISP is still sending and receiving all of that data for you.
Step 2) Block VPNs to prevent circumvention of your rate limts
Step 3) Profit?
I don't see this happening, but I think that's what the comment you were responding to is suggesting.
If I rate-limit VPN outright, I'm an ugly dictator bent on destroying privacy.
If I rate-limit popular bandwidth-intensive traffic, I'm just a guy trying to keep network usage fair for every user. If that involves limiting VPNs as well, they are simply collateral damage, the end justifies the means, and I'm still a good guy.
You're talking here more about avoiding the preferential site-by-site traffic-class-based shaping that goes on when Net Neutrality is not enforced. Which doesn't really happen, because it's far easier to just have a thinner peerage link between the ISP and the content-provider in the first place, and then do regular QoSing on that thin pipe with priority to the people on better plans. (The result is exactly like telephone service on New Year's Eve: local calls go through just fine, but long-distance calls mostly fail because the POTS peerage links are saturated.)
What prevents companies from artificially slowing things coming from known VPN endpoints?
Time Warner affiliates would charge you an additional $20/mo for business access.
For example, US doesn't have to block access to online casinos - they just order the banks and financial institutions not to work with such sites.
But Russia doesn't have such authority over Facebook or Skype. It cannot issue a NSL to Google for example. Therefore they are looking for other methods of controlling those companies (such as laws requiring to keep russian users' data in Russia).
China blocks many foreign web services and as a result they have their national messengers, search engine, social networks that will comply with national laws.
I do not approve Russian or China (especially China) policies, I just want to notice that Internet being an international medium without borders and customs creates new problems for applying national legislation (like taxation or spreading information violationg the laws).
The government may not need to decrypt or block most traffic, but telcos will want to extract a levy for various uses of their circuits. Using the argument used against Netflix, why should your employer just be able to benefit from pushing ActiveSync down to your phone without paying Verizon?
Since when have western leaders ever taken policy direction from Russia?
It's not a reasonable tradeoff and I disagree with him, but one can easily see why someone in his position would be concerned about this for reasons other than attempting to secure a dictatorship.
The fact is the US government has a well documented history of undermining elections, and then funding rebellion and civil wars if the election doesn't turn out how they hoped. When leaders attempt to shut down mediums used for propaganda/psyops/adversary coordination, they get to play the fascist dictator card against them, which is pretty convenient.
VPN services can't exactly hide behind being an impartial carrier since they sell themselves as tools precisely for circumventing censorship, tracking, region locking, and providing anonymity.
I've said it before and I'll keep saying it, this is a political problem that can't be solved through more tunnels.
I really wish some VPN providers would try advertising themselves as desirable technical solutions to the technical shortcomings of many ISPs -- e.g. my ISP here doesn't give me native IPv6, and has a crappy last mile. OpenVPN-over-UDP helps with both.
VPNs can also simply protect against attacks on public networks in e.g. cafes, libraries, airports.
> this is a political problem that can't be solved through more tunnels
Yes, but they help in that they increase people's headroom for informing and acting.
To expand on that, you could argue this for any network, even home and company networks -- who knows which of the many windows computers and android phones of my colleagues/family are bots?
Yet in the past few years we had hundreds of people jailed and/or fined for the content they posted on social media or even for reposts and likes. Yet the morons do not learn. Can't wait for Yarovaya's law to come in full effect.

Did this affect to ransomware collector too?

The Tor Browser already comes with the meek transport[1] that uses domain fronting, one with Amazon and the other with Azure. There's also a recent PT titled snowflake[2], that uses WebRTC to connect to short lived proxies that people can make by just running some JS code in their browser, it's currently available in the alpha builds for Linux and Mac.
Note that meek is expensive, and the Tor Project pays for each byte. It should only be used when no other PT works.

As with everything else, this isn't a 100% technical solution, it has a political component of how expensive the fronting website is to block.
If you are able to set up a personal openvpn server, they wont bother hunting you down.
