It's trivial to set up a mail transport between physically separate
networks using a pair of PCs with modems and local network connections.
They don't have to be fancy, either - a tiny Unix installation with SMTP
and UUCP is all it takes.  I've done it with Minix on a 286 box.  Today,
I guess a Raspberry Pi with a USB modem might be chosen, or a laptop
that could be hooked up to open WiFi networks to do the SMTP side from
somewhere other than its operator's home.

To avoid the modem link, you'd need some safe way to transport e.g. a
USB memory stick with the mail spool on it between participating hosts.

Of course, he'd still need a network.

I think the point about email is that it is inherently store-and-
forward, so it can relatively easily be moved off a network, stored,
moved by other means, and put back on a (possibly different) network.

I believe he meant similar to *nix boxes where you could 
just copy the files in $HOME/mail (or where ever it is) 
onto media and once the data is out of the country it can 
be copied onto another mail system's $HOME/mail and then 
shared with the unblocked part of the internet.  Not a 
user account on somethingmail.com, but rather the entire 
$HOME/mail of all accounts and mailed to someone else who 
is somewhere else on a regular basis.  Also, the reverse

A good idea either way.  KISS works. :)

Quoting a journalist, so

https://www.theguardian.com/world/2019/nov/21/irans-digital-shutdown-other-regimes-will-be-watching-closely

First quote out of order from the article:

"Internet penetration and complexity has vastly grown in Iran 
over the past decade, but the country’s users still connect 
to the global network through just two gateways. Both are 
controlled by the regime, and can be blocked when it chooses."





"Access to the internet is gradually being restored in Iran 
after an unprecedented five-day shutdown that cut its population 
off from the rest of the world and suppressed news of the 
deadliest unrest since the country’s 1979 revolution."

"The internet-freedom group Access Now recorded 75 internet
outages in 2016, which more than doubled to 196 last year."

"Iranians were cut off from the global internet, but 
internally, networks appeared to be functioning relatively 
normally."

"the Iranian government has been working to develop the 
so-called “halal net”, a closed-off version of the internet 
similar to China’s “great firewall”. Iran has been 
pressuring businesses to shift their operations inside the 
country on to what it calls the National Information Network, 
which now boasts its own banking platforms, industrial 
services and messaging apps – ones that activists believe 
are closely surveilled by authorities."



"The Trump sanctions have actually made it easier for Iran 
to seal its citizens off from the global internet ... Many 
Iranian tech firms have been left with no option but to use 
the Islamic Republic’s internal network and infrastructure 
instead."  (reordered quote)

"The last time Iran attempted to choke off access, during 
unrest in January 2018, it was forced to open connections 
again after just 30 minutes, Rashidi says.

“It was a disaster,” he says. “Nothing was working: all 
the government offices, hospitals, financial services 
were gone ... they’ve discovered a lot of things do need 
access to the outside world”

This time, it appears to have gone more smoothly: two 
sources able to monitor internet traffic inside Iran 
confirmed to the Guardian there was no significant 
disruption, indicating hospitals, financial software 
and even ride-sharing apps were still able to function, 
even as Iranians were unable to connect to websites 
such as Google."

"Other authoritarian governments are pursuing a similar 
path. This month, Russia implemented a new law requiring 
ISPs to install equipment better able to identify the 
source of web traffic, as part of a strategy to one day 
be able to completely re-route the Russian internet 
through state-controlled data points."

  :)

“Regimes around the world will be watching very closely

international community,” he says. “If it turns out

Re: Iran cuts 95% of Internet traffic

[Sean Donelan]

Digging a little deeper, it looks like Iran's blocking is more complex 
than I've seen before.


Consumer/mobile networks appear nearly completely blocked.

However, many important business/financial networks and B2B traffic appear 
operating normally.


I don't yet have good data about of the granularity of the blocking.  But 
the Iranian government is not using the typical blunt cut-off of 
everything we've seen in other countries.

The wierd thing to me is the one thing governments are afraid 
of is people talking to each other without restriction.  Not 
this or that, rather just people talking freely.  WTF...

I guess all these governments who like to control access so tightly are going 
to be in a total tailspin over Starlink eh.

Implementation specifics vary. Most rely on state control of consumer ISPs
and implement a variety of systems at that layer. Many also have
chokepoints for international connectivity as well.

Penalties for evading the censorship regime? I don't know specifically what
those entail, but probably at the very least fines and confiscation of
equipment, possibly imprisonment, or even worse in some places? Scanning
for RF emissions on common communications frequencies isn't particularly
difficult, nor is police just looking around their jurisdictions for such
antennas on the exterior of buildings.

Of course, there will always be ways around these sorts of things for
people who have the means/resources/technical capability to do so, and some
will be much harder to get caught with than others. But the 0.01% of people
who have the means and resources aren't the real target anyway, as many
people with the means are people who already have a lot to lose and hence
tend to remain loyal to the state to begin with. The 0.01% who have the
technical capability to do something like build a unidirectional
transceiver from parts and deploy it in a way that it won't easily be
detected are a small enough group that they can be written off. It's the
other 99.8% whom they're worried about and against whom censorship regimes
have the best overall efficacy.

Its very practical for a country to cut 95%+ of its Internet connectivity. 
Its not a complete cut-off, there is some limited connectivity. But for 
most ordinary individuals, their communication channels are cut-off.

Does anyone know the network mechanics of how this happens?  For
example, do all fiber connections go through a governmant choke
point for suppression?  If so, what's to stop ubiquity-style 
microwave over the border to sympathetic folks on the other side?

Though Iran's situation is hardly a new advent, it reminds me that
more and more countries seem to be going for the centralized
filter/control/kill option and what a sad development that is. It sure
seems like this is going to vastly change how inter-nation traffic (or
at least inter-continental) is exchanged between providers and even
how bandwidth is sold. It feels to me like it won't be too much longer
before such things start to become somewhat less a matter of business
and more a matter of treaty.

Iran cuts 95% of Internet traffic

[Sean Donelan]

Its very practical for a country to cut 95%+ of its Internet connectivity. 
Its not a complete cut-off, there is some limited connectivity. But for 
most ordinary individuals, their communication channels are cut-off.
