And even in this case you can't rely on your domain registry not to change your DNS without your consent. And there's not really a big chance you own a dedicated IP address.

Why would your domain registry change your DNS? You can also add multiple NS to a domain.

Additionally, if you're on a business plan then you can get a dedicated IP from your ISP or just host in a data center.

There is JetBrains toolbox for that, for server products there are some tools as well

The only place when you really need semicolons Kotlin are the enum constants, everything else can be considered "strictly no semicolons", so pretty consistent.

Would you mind sharing the approximate number of issues and active users in your JIRA install?

It varies widely. We have ~300 users, 30 projects, probably on the order of ~20k tickets. Performance has been up and down, occasionally things slow way down and we have to file a ticket and then they come back with some excuse about re-indexing or relocating the instance. Normally it's pretty acceptable, but it feels like there are a ton of a variables that go into its performance day-to-day and minute-to-minute.

I'm at a medium/large company, but without access to real numbers i'd say off the top of my head its probably >500 users across 100+ projects and 10s of thousands of issues.
