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...

Every once in a while I'm reminded I should explore my own Twin Cities more. Last week I ended up at a cute watch repair place and finally tried Ed's Lebanese Deli (it's inside a Super USA gas station). I know, I know. Just trust me.
