I need a VPS for a service that runs 24/7. Traffic is roughly even throughout the day, but even an hour of downtime is undesirable.

In terms of resources, I'm thinking about 4–6 CPU cores / 16 GB RAM / 150 GB NVMe.

When making my choice, I'm currently focusing more on infrastructure reliability, backups, and support. hostpro.com is among the options.

What do you look for first and foremost when choosing a VPS for a service that can't simply be "shut down for the night"?
