Were they cut on purpose or accident?

Cables in Red Sea got cut frequently. All the time it's the same story - anchor dropped where it should not. Similar stories happen near Singapore.

On land, we’ve call before you dig. I wish they could do something like call before you drop (anchor) training or just get the word out.

They are usually marked on nautical charts.

Multiple subsea fiber cuts in the Red Sea impacting global communications Impact Summary Starting at 05:45 UTC on 06 September 2025, traffic traversing through the Middle East originating and/or terminating in Asia or Europe regions may experience increased latency due to multiple undersea fiber cuts in the Red Sea. The disruption has required rerouting through alternate paths which may lead to higher-than-normal lat…

The smart folks who keep these things running, despite failures like this, are incredible. Hats off to you all, good luck in the coming weeks as you have to deal with this.

(It’s not actually anchors.)

Why do you say that?

I can't say I'm an expert on the matter, but my understanding from industry reporting on some likely intentional ones in the Baltic where that they were still unambiguously done with anchors. Just by someone intentionally causing the anchor to drop and drag along.

Can they splice these? Surely the don't have to run a whole new cable?

I've only done land based fiber design, but I would assume based on my experience in that field that one of two things happens.

First option, there's some slack somewhere nearby to do a pull nearby.

If you ever pay attention to aerial poles, you'll see at various intervals things that are vaguely reminiscent of a snowshoe or tennis racket, in the industry they are in fact informally referred to as a 'snowshoe' and the entire purpose is to have some fiber to 'release' if a cut happens and a resplice is needed. [0]

I'd -assume- there is an analogue for these in undersea cables...

If not, well then you'd have to splice a length in and probably have the right sort of mechanism to ensure the cladding/etc stays contiguous (maybe even weld? IDK) but regardless you're probably talking... Actually wait yeah they've got this all figured out; https://www.youtube.com/watch?v=QiwidMEv8CM

[0] - Real world example, for instance if someone uses a fiber splice can for target practice.
