+  - Company information
+  - Links to other places etc
+- Been around for a while
+- In 2022, we restructured the content
+  - Make it easier to find things
+  - Remove duplication
+- This didn't quite go to plan
+- One afternoon, I was looking to reference a process, and couldn't find it

 # Conclusion
 
+<!--
+- With a few hours work, the pages were back
+  - There was no downtime
+  - No content freeze
+  - No data loss
+- Most people didn't even know there was an issue
+- I've used this trick a a few times in my career, for both Wagtail and plain Django sites
+  - Ironically, just a few weeks after the blog post was published
+  - Works identically for Django sites, so long as you know how to reconstruct the delete query.
+- Hopefully this helps you out as much as it has me!
