I hate to say it but I recently moved away from Linode after their /64 block in Frankfurt was banned by all Google services. And even though all their kubernetes nodes have a public ipv4 address they were somehow unable to fallback on this when their ipv6 didn't work.
And when I suggested this to their support they acted like I was crazy and said there is no way to switch between ipv4 and ipv6. Well I don't work in networking but I do work for a major telco and I know our networking guys could have done that routing change, easy.
We blocked the entire of Linode AS63949 ranges because we were getting attacked from random owned nodes and it was tripping our IDS constantly. Just got fed up with it in the end and decided to hose them.
To note, we have had problems with AWS blocking random addresses as well where we've had staff abroad.
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.
