Audit legacy docs 404s

[Devon-White]

Docs Redirects & 404 Investigation

• Investigate the spike in 404s around April 4
• Audit old docs redirects that produce 302s
• Identify redirects that land on 404 pages
• Confirm whether FreeSWITCH docs are still on old infrastructure
• Create a report capturing:
  • Broken source URL
  • Current redirect target
  • Final status code
  • Correct destination
• Prioritize high-ranking / high-traffic broken pages
• Add automated checks for docs redirects (Fern handles)
