Do they actually say they don't have a slave to that database ready to take over? I seriously doubt Let's Encrypt has no spare.
Note I didn't say you shouldn't run one service (as in daemon) or set of services from one box, just that one box is not enough and you need that spare.
It Let's Encrypt actually has no spare for their database server and they're one hardware failure away from being down for what may be a large chunk of time (I highly doubt it), then I wouldn't want to use them even if free. Thankfully, I doubt your interpretation of what that article is saying.
You're right, from the article:
> The new AMD EPYC CPUs sit at about 25%. You can see in this graph where we promoted the new database server from replica (read-only) to primary (read/write) on September 15.
