Bad luck Ed.
And to think that I know of some people running hot masternodes on spot instances. Lets hope they've got backups

Are people still running hot masternodes? Why?

Have you ever tried running 70 remote setups? It's a maintainance hell...
I only realised how much easier it is to manage hot nodes when running testnet masternodes. Still, I'll stick with cold for now. I'm quite a way from 70 masternodes.
