Monero currently has +/- 150 nodes. So significantly less in numbers. Would such an attack be feasible? And what would happen if such an attack would last for some time?
I can as well imagine a scenario that most nodes are under attack, except the potential malicious one of the attacker.
Let's try to get high-availability, high-performance Monero nodes spread as widely as possible.
Ideally, we'd have one or two in every data center (and behind every anti-ddos specialist) on the planet. Not that AWS is anything great, but the concept/execution here is pretty slick: https://classic-cloud.net/
But how about first filling in the largest holes in global/political/demographic coverage, as according to https://monerohash.com/nodes-distribution.html?
We could start 'adopting' countries and putting up nodes in their capitals.
I propose prioritizing Australia, Bangladesh, Brazil, Colombia, Costa Rica, Chile, Egypt, Iceland, India, Indonesia, Iran, Israel, Kuwait, Mexico, New Zealand, Nigeria, Pakistan, Philippines, Thailand, Turkey, UAE, and Vietnam because their local nodes-per-citizen ratio is zero and for several international bandwidth is at a premium.
