True, but that is a little exaggerated. Yes, they were hacked in the past (over a year ago); one of their small data centers went down. Their US East center has been solid for the past 8 months that I have been using, no hiccups.
As opposed to AWS and DO which have never had comparable security issues. In this case, "never" is what I'd expect versus "yeah it's been a few months since last serious incident".
I wouldn't host an ethereum or bitcoin node on Linode. If I were a PCI auditor I would think pretty hard about compliance on the platform.
That said, blog you don't care too much about -- sure!
I wish I could say the same for US South (Atlanta). Constant DDoS attacks, outages, power failures, hardware failures, and more. I don't think I've ever gone longer than 3 months of uptime there across multiple linodes.
