Kertoo lähinnä, kuinka heikoilla jäillä ollaan, jos selittelyssä mennään tasolle "en ole salaliittoteoreetikko, mutta..."

Ehkäpä ne afrikkalaiset hakkerit taas. 😆

Have to say, their PR efforts have been exemplary during this case.

🇺🇦✈️ Zelensky has left the U.S. early and is now heading to London, where a meeting of several European leaders is set to take place tomorrow. Prior, he will meet with UK Prime Minister Starmer.

Who has been screeming bloody murder (in addition to the regular crowd who think even every sprained ankle is Krem's doing)?

Why it has to be someone on-site in order to detect this deviation?

Submarine cable operator are able to monitor cable remotely and based on previous cases, they are able to locate e.g. fiber optic faults with an accuracy of tens of meters remotely.

IMO this makes it unlikely that Telepaatti found that damage.

They have several ROVs.

'Discovered' could mean that Cinia noticed it during normal monitoring.

How close to Sealion was Telepaatti on Wednesday? The most likely don't have several hundred meters of cable for ROV...if they even have one.

But that is solely Your assumption, right?

Based on the interviews given to Yle, Cinia does not have exact information about the damage. They suppose e.g. a scratch on the protective cover could cause this. Wording indicates that the damage has not been detected by that vessel or its ROV.

Could that lifting etc. needed for LV-SE cable repair be the reason for damage? It is older cable than Sealion, so LV-SE would be under it.

Paper in this post recognizes 8 cases in relatively short time, seven of them in relatively small area.

But that is totally different discussion; can a single incident be an accident vs. can all be accidents. Mixing these is purposeful, or even misleading.

There can be 10 or 50 safety mechanims, but still there has been actual incidents that have been accidents. No bullet proof systems exists.

In spite of several safety systems, accidents do happen in every industry due to technical failure, lack of maintanance, human error, neglect or combination of these. Maritime transport sector (or anchors) is no exception.

Denying this is usually seen as part of problem, not as solution.

It has happened several times before these incidents and before current geopol tension (i.e. unlikely state motivation).

Marine ins. companies recognice this possibility based on their actual cases.

A number of captains have told to their Finnish colleagues in public about these kinds of insidents

There is also a substantial risk of bias in this type of argumentation; Seamanship is easily assessed based on one's own high standards, even though the reality is something completely different in these rusty buckets.

IMHO Vezhen case had a salutary effect on the public debate, but also on expert analysis in general; suddenly impossibility became possible and intentional damage/sabotage became negligent/accident.

The changes made by Elon's coders are focused on "creating new paths to block payments and possibly leave less visibility into what has been blocked."

The changes made by Elon's coders are focused on "creating new paths to block payments and possibly leave less visibility into what has been blocked."

This is a backdoor. Elon's coders are creating a backdoor into the US Treasury. This is incredibly dangerous both because of its intended use (by Elon and Trump) and the risk of other actors exploiting a major security vulnerability to cause a massive disruption to the US government.

Significant wave height - Finnish Meteorological Institute How the significant wave height and the highest individual waves in the sea are defined.

That ain't the highest single wave but significant wave height.

This means per definition that the highest single wave is most likely ~ 7 m.

Does 2.6 m wave mean 'significant wave height', 'biggest significant wave height during her voyage' or actual 'hightest single wave', which can be ~2× the hight of 'significant wave height'?

Where is this wave data taken from?

Danish Airforce published statistics on their Quick Reaction Alert (Afvisningsberedskabet) rejections of Russian aircraft heading towards Danish airspace.

Though last year seems to be a record year, there have been no violations of Danish airspace since 2022.

Ships exact route (i.e. actual water depth ), hull shape, speed, and draft greatly affects this effect. Tankers are most prone to this.

Åklagaren häver beslut om beslagtaget fartyg I den pågående förundersökningen kring ett kabelbrott mellan Sverige och Lettland i Östersjön har det klarlagts att det inte rör sig om ett grovt sabotage. Ett beslut har fattats om att häva beslaget ...

Swedish Prosecutor press-release:

Vezhen is being released.

The statement says the latest cable cut in the Baltic wasn't sabotage, but a result of weather conditions, faulty equipment and poor seamanship.
