Digi and OpenNet are both pretty fast and reliable on fibre. I find Smart 4G mostly good but gets slower/congested in the evenings in PP, even worse in Kampot where it once slowed to about 0.25Mbps when I was there visiting, but I don't know if they just had a problem on that occasion or if it's a regular occurrence.

Here is a map and list Cambodia's submarine connections. There are three submarine cable links, as noted on the righthand side of the map.

Do you understand how peering and core routing works (for example BGP announcements)? NTT and Telcotech are the only providers in my knowledge that own submarine cables connected to Cambodia. The other providers lease lines from and peer with them. There is land carried connectivity too.

If you are interested in traceroutes for different AS I can happily run them for you from different providers, but as you'd know those routes change pretty often and we haven't even differentiated v4 from v6 yet. If you don't know what that means then you're probably asking the wrong questions here...

Aha...

You can't just translate which cable you think an ISP is using to decide if it's good or not. That's not how it works. The problems and bottlenecks you'll encounter will hit you way before your traffic is even thinking about being peered internationally.

No, but I get it.

There are a variety of routes, load-balancing, etc.

Question, though:

When 1 of the major submarine cables get cut, say, AAE-1, AAG, MTC, or SJC-2, which ISPs lose most of their functionality?

AAE-1

AAG

MTC

SJC-2

Valid question, I believe, since some ISPs do not have redundant links to other lines for that eventuality.
Some only give VIP accounts backup lines.
And some say they do, but really don't.

Help us out here, will you?

I know it can be complex, but can you boil it down for us?

And which ISPs are land-carried and reliable? Expensive some?

%) all this technical talk is way over my head but after 3 years of Metfone fiber connection in Kep I can say their promised speeds are always kept or even faster when I do the speedtests and outages are usually resolved very quickly.

Absolutely it's a valid question. Drinking when AAG is disrupted has been tradition for a long time in some circles, news articles over the years show what a piece of shit it is:

https://vietnamnews.vn/society/392855/t ... sYdXMYA.97
https://e.vnexpress.net/news/news/disas ... 64615.html
http://english.vietnamnet.vn/fms/scienc ... etnam.html
http://www.thesundaily.my/news/2017/09/ ... connection

When it breaks and people's cat images take other tubes those tubes quickly become overloaded by the sudden increase in traffic from the re-route affecting all traffic in the region.

Right now I think Sinet has most error prone peering through their Korean IPv6 lines.

Thanks, Fax.

With improving wireless technologies for casual use penetrating remote areas with bad infrastructure problems (like Cambodia and Africa, haha), my guess is that the only (un)thinking blocking people are new highrises and existing contracts. (<-- SMALL EDIT: I added to the typo, haha. I meant 'thing', not 'thinking' , but it sounds better, in my opinion).

What do you think of wireless technology used by like SEATEL, 4G/LTE, 4.5G (?), and Kingtel for coverage and reliability in Phnom Penh and Cambodia?

Those land and marine cables, though, are getting better in SE Asia, however.

By the way, what do you think in mid-2018 of the various fiber providers, like Digi, Open Net, Online, Metfone, EZECOM, MekongNet, SingTel, etc? Also NTT or NTC?

Anyhow, let's not all jump on the same network at once, haha, since that happened to OpenNet earlier and they couldn't scale up fast enough, haha!
