Pass a URL to ping a website and see if response is a 200. If it isn't, you get an email with the error response received.

Tip: Make a new, separate cron val to call this isMyWebsiteDown() periodically to check the website's health every 15 minutes or so.
Your separate cron val's code will look something like this:

//Import this val
import isMyWebsiteDown from "https://esm.town/v/dvsj/isMyWebsiteDown";

//Add all the websites you want to check
isMyWebsiteDown(`https://dvsj.in`);
isMyWebsiteDown(`https://blog.dvsj.in`);

export default {};

Emails me if my personal website is down. (If you fork this, it'll email you, since you'll be the owner of the new fork.)
