[0] Linode got DDOS'ed literally entirely off the Internet in December 2016. You can't take AWS down with a DDOS. You can take down an individual customer server but you can't take AWS offline with a DDOS.
A while back I made a stupid mistake while tired, and I was panicking and couldn't find the feature I needed in the account.
I called Linode at around 11PM CDT, and got a helpful friendly guy on the line who walked me through what I needed. I was amazed that I could get a human on the line in less than a minute after hours, when only paying $10/month.
This is probably the most reasonable risk mitigation you can fairly easily do.
I don't think there exists a vendor that's going to be foolproof. Most users aren't going to any have issues with any of the major providers, including DO, Linode, Vultr, Oracle, AWS, Azure, etc...
