Side note curiosity... I noticed your html tags were WordPress and that your site resolved to Godaddy servers. So I looked at Godaddy's Wordpress hosting costs.[1] I see that Godaddy's $6.99 price tier says it's appropriate for ~25k monthly visitors.

It would be interesting to see what your traffic stats were that caused the "503 Service Unavailable error" and "Resource Limit Is Reached".

[To the downvoters, did I ask an inappropriate question about web hosting?]

(I see that your live website is back up and the page transfers ~426kb. So multiply by 25k is ~10.7 GB of bandwidth. Following your comment about Netlify, I see that their $0 tier includes 100 GB of bandwidth.)
