The site is running on a Intel NUC at my home, and has been up for about 2? years now, and i have no intention of taking it down, since my own team uses it on a daily basis.
The only reasons for this site to go down are: the datasource becomes unavailable, my house burns down, my company goes bellyup, the dykes break and the Netherlands slide beneath the waves, or my car experiences an unplanned 100G decelleration.
None of the above are likely anytime soon, so i'd say you're safe using the daily download.
But even if my site goes down, you could always download the data yourself using my script in the article 😉
