There's no good excuse for ANY website or platform these days to not be able to handle this amount of traffic with absolute minimal effort. In fact, handling 10x more should be trivial (and cheap).
You can design it to be light and fast, but you wouldn't know unless you test it right? Good to know that a cheap droplet can at least handle rendering the landing page though.
There are a lot of factors that go into site performance. Knowing your site can handle what other people have seen is a good start.
