There is an assumption that if there's nothing really visible made by one person it means they don't know what they are talking about. So, background: I'm a linux sysadmin at a very large internet company, and has been running hobby and small business sites for 20 years parallel to this. About a decade ago I wrote cache plugins for WordPress and run a lot of tests of 128MB VPS machines to see when they break. The traffic from neverssl.com really should be fine on a Raspberry Pi 4, because the whole app, including the temporary redirect db needed would easily fit in memory. The OS can be read-only, so the SD card wouldn't wear out either, and the Pi 4 has a Gbit link. But as it's been pointed out, the internet uplink could indeed be a problem, so instead of that, there's Hetzner: 33€/m gets you unlimited traffic, 2GB RAM, 320GB HDD. That's 400€/year, and that's all the cost. Note: Rpi4 has 1-4GB RAM.

Next time please consider that people may actually know what they are talking about even if they don't have their name attached to an "internet scale" service.
