After several years of almost doing the migration process, I'm finally shutting down a Scaleway instance (from November 2016!!) and migrating it over to Hetzner, which has already shown a very positive performance increase. I'm sure if I kept it in Scaleway, their new instances would be better, but I've got a few other things in Hetzner, and it makes managing easier, as well as a better price point, too!
