Additionally, is websites just another word for servers?
If by websites you mean instances, then currently close to 1250. Here is a list of them for you.
Oh my goodness.
A good place to look (not limited to just Lemmy instances): fedidb.org
The Fediverse is essentially a collection of platforms (such as Lemmy, Mastodon, Pixelfed, and more). Each platform has a number of instances that are hosted separately, hence the decentralized nature of the Fediverse. For example, Lemmy is a platform, and Lemmy instances include Lemmy.world, Lemmy.ml, kbin.social, sh.itjust.works, and more. Others have posted links to lists of instances that you can look through.

They are called instances. One instance can have multiple servers as backup.
Example: An instance can have a server in New York State and California, if the New York server caught fire, they can redirect you to the California backup server.
So servers are sort of batteries for instances/websites, right?
Youre right. “Servers” are just computers that do all the work behind a website.
But when it comes to lemmy people sometimes use “server” and “instance” to refer to the same thing: what lemmy.ml, lemmy.world, and others are.
Which, let’s be honest, is not the case with most instances… not trolling, just saying 🤷.
That kinda sucks, but my point was to clarify the terminology, not claiming that some Lemmy instances have multiple servers.
And one server can host multiple instances 👍
