Initally some local site, then I transferred to GoDaddy, then to OVH (since GD is shit). One is still at Cloudflare (tried to move there, but they don’t support al TLDs that I use, like “.eu”).
For DNS I use Cloudflare. They provide a layer of privacy, i.e. your server IPs don’t get exposed directly.
More efficient or even lossless, sustainable energy storage.
