The significance of the number of nodes contributing to the decentralization of hardware in the Lightning Network is noteable. I'm glad to be learning how to thermodynamically ground the economic energy of my time and freedom in an increasingly secure way. Running a node also means caring for the link between the virtual and the physical, to have an environment in which the hardware can run, in order to transact economically in the digital realm. I'm researching the security aspects.

Question: How is it that after one month online with no downtime, a Lightning Network node ranks in the top 500 nodes in availability according to 1ML?

a) Would it be correct to deduce that the number of LN nodes which are online 24/7 (all the time on a given month) is about 500?

b) If there was a major security update during this time, would it be correct to assume that roughly 500 nodes did not update during this monthly period if the ranking "drops" above 500 for even a 5-minute downtime during an entire month?

c) 500 seems to be a small number for such a large global venture - and vulnerable to simultaneous attacks by a learning algorithm from an APT distributed bot swarm which feeds on the 1ML JSON dataset API.

Anywhere there is a war, poverty, ecological destruction and a lurking misaligned quantum artificial intelligence - the likelihood of a safe node environment with electrical availability is critically impacted by these threats.

Perhaps the best mitigation at this time, and assistance to those in unconductive environments, is a continued coordination of decentralized hardware in the Lightning Network and knowledge of its significance.
