I've used Digital Ocean (and many other hosting providers) for as long as most of them have existed. Most of my servers have been running nearly uninterrupted for many years. Yes, there will be a reboot or move every so often but the uptime is incredibly high.

The idea that single server is capable beat the reliability of a massively distributed system is counter-intuitive and yet usually it's the case.

The average distributed system is a house of cards that can come tumbling down if any one of a number of pieces fails. The average static server is a rock of stability, with very few failure modes.
