Idea

Create a GHA to run on a recurring schedule to validate that the company websites return 200 status codes. Other status codes should prompt the action to open a pull request removing the website.

We might be able to utilize test.websites.ex

Pros

• Keeps the site current with active and reachable company sites

Cons

• We could remove companies that may have been acquired.
