Data from the IODA project shows there was a complete drop (no prefixes seen via BGP) from AS43852 but looks like it has since been restored. I think it would depend on how well any other ISPs in the area were still functioning or availability of satellite connectivity as to how usable Bitcoin/LN were during the outage. https://i.nostr.build/3YXA3dcjJ5qiMst9.jpg
yeah it will be INTERMITTENT and more can happen soon was escalation continue. - local LN mesh can may work with some TRUSTED authority but MAINNET will FAIL if cannot reach 3 or more peers.
