I never said it was "nefarious", I'm saying it was badly handled and it brought down all services in an entire location for days, with no fallback to ipv4, no status communication from Linode.
It's not malice, it's just incompetence.
Why the block was banned I have no idea and I don't really care, it can happen and they need to be able to handle it.
I literally had a support case asking what happened, no response, eventually I had to say "look, I'm moving now because all services are down, please tell me what is going on", no answer, I had to move to get my services back up.
This was resolved and it didn’t appear something nefarious or any kind of ban was going on, so if you have some references I’d love to see them
