The Greenland sea cables are probably being closely monitored, but redundancy seems minimal likely limited to OneWeb satellite connectivity and some VSAT links.
Looking at the routing side, AS8818 announces just two /19s and one /22 (and two /32s in IPv6) with a single upstream provider, Level 3 Inc. This suggests that Layer 3 redundancy is even more constrained.
I would have expected at least one EU-based provider as an additional upstream...

Submarine Cable

5404 kilometers of high-tech fiber optic connection, is the description of Greenland’s first submarine communications cable Greenland Connect which went into operation in March 2009.

It runs from Newfoundland in Canada to Nuuk in Greenland. From where it continues on to Qaqortoq and Iceland. With a response time of just 23 milliseconds, it is one of the fastest routes across the Atlantic. The second submarine communicat…

“If the question that broke McCarthyism in the 1950s was "Have you no sense of decency, sir, at long last?” then Trump’s answer today would surely be, “No, none at all.”

In that key exchange, McCarthy was accused of “reckless cruelty.” Yet, within Trump’s orbit, recklessness is a virtue. Cruelty is celebrated.

Trump’s supporters like to suggest that he is a modern-day Caesar. In truth, he more closely resembles Caligula, the cruel sadist whose motto was oderint dum metuant — “Let them hate me, as long as they fear me.”” - @…

So, tonight's goal is to continue with ngscopeclient performance work.
I started out by doubling the speed of the eye pattern *again* by moving index buffer calculation from CPU to GPU.
Next up is going to be getting the 100baseTX decoder to not be so slow. Right now of the 43 seconds of CPU time in the current 1-minute benchmark, 26.9 is spent sampling the MLT-3 waveform on rising edges of the recovered clock.
The thing is, we already *know* the sample values at the re…

If I have the current state of a LFSR and the polynomial, is there an easy way to rapidly run it an enormous number of iterations (e.g. millions) into the future without calculating every intermediate state?
