Many people will respond that "one big server" is a massive single point of failure, but in doing so they miss that it is also a single point of success. If you have a distributed system, you have to test and monitor lots of different failure scenarios. With a SPOS, you only have one thing to monitor. For a lot of cases the reliability of that SPOS is plenty.

Bonus: Just move it to the cloud, because AWS is definitely not its own SPOF and it never goes down taking half the internet with it.
