I pointed my link checker at 20 popular docs sites. It accused nearly all of them, and it was wrong.

A link checker script incorrectly reported broken links on popular documentation sites due to its inability to handle network failures and rate limiting. This highlights the importance of a link checker being able to distinguish between a broken link and a network failure. To fix this, the script should be updated to handle these scenarios and provide more accurate results. Engineers should consider implementing this update to ensure their link checkers are reliable.
