Interesting that latency between Cape Town and Seoul actually improved (decreased) as a result of the cable cut, due to traffic being allowed on a more direct (and more expensive) route between the 2 cities.<p>More examples in Slide 10 of <a href="https://www.linkedin.com/in/dougmadory/details/featured/50016397/single-media-viewer/?profileId=ACoAAABgDfMBQqg6K3WmEobvLYAvoetjdTSF-R0" rel="nofollow noreferrer">https://www.linkedin.com/in/dougmadory/details/featured/5001...</a>
Nothing interesting to add, just an anecdote.
As someone based in a semi-rural part of South Africa, this dual cable break was a huge PITA for a few days. Latencies went through the roof; remote work was made very difficult.
I read "submarine cables" and imagined a sort of monorail or guide-wire for an underwater vehicle. I thought, "I guess that makes sense, that'd probably be cheaper or safer than an untethered submarine".<p>It's funny how "good" the brain is at rationalizing misconceptions like that.<p>If I hadn't read a couple comments to try and see why Africa (or anyone) would need a safety-rope-assisted underwater submarine I might have gone on assuming that was just a normal thing.
Due to some inane regulations there is only one ship that can fix the cable break and it was busy over 8000 km away fixing another cable break - will take a week to get onsite.

> <i>According</i> to him, one of the cables had been dragged "over a kilometer"<p>Undersea landslides can go for over a hundred kilometers and can last hours.<p>So I'm not sure why this is impressive or in question?<p>It doesn't seem unlikely to me.
