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 communications cable is Greenland Connect North and runs from Nuuk through Maniitsoq and Sisimiut up to Aasiaat.

"The break in Cinia's C-Lion1 submarine cable has been repaired and the direct submarine cable connection between Finland and Germany is back online and fully operational."

Impressive!
