Hi @anthonypkeane & @iccub. Here's comments for each of the error messages:

• "This page isn't working" … lgtm. No changes
• "This site can't be reached" … would be nice if we could give the user some recourse, e.g. "Try re-typing the URL, or opening a search engine and searching for the new URL." But if we can't, message is OK as-is.
• "No internet" … suggest changing the title to "No internet access" and then prefacing the bullet points with a line that says "It appears you're not online. To fix this, try:"
• "Your clock is ahead" … suggest changing this title to "Your system time is wrong" and then changing the CTA button to "Update date / time"
• "Connect to network" … lgtm. No changes.
• "Did you mean example.com?" … lgtm. No changes.
• "The page ahead may try to charge you money" … suggest changing title to "The page you're trying to visit may charge you money"
• "Your connection is not private" … lgtm. No changes.
• "Deceptive site ahead" … lgtm. No changes.
• "The site ahead contains malware" … suggest changing title to "The site you're trying to visit contains malware"
• "The site ahead contains harmful programs" … suggest changing title to "The site you're trying to visit contains harmful programs"

Note to QA: Not all copy could be updated. I updated what I could.
As long as there's typos, nothing to verify 1:1 by qa in my opinion
