Issue Summary

Garbled text after saving manually written changes in edit mode

Steps to Reproduce

Description of problem:
When making a fairly large edit of an existing Confluence page in my personal space, the update was mangled, and no error was thrown by the UI. Only the newly-changed text was mangled; existing text was not changed. One example of many throughout the page.:

I edit this page frequently (3-4 times a week) and have for months. This incident was the first (and so far only) time this has happened.

Suggestions to Atlassian to improve:

Collect metrics and artefacts from OCI to help root cause the problem

Consider an update to the save page workflow to validate the changes saved to disk match what was sent from the browser. Potential implementations include a byte-for-byte comparison [ Othumbs down in time and O(1) in space ] or a comparison of a checksum using an algorithm with a low risk of hash collision, e.g. SHA-512 [ Also Othumbs down in time and O(1) in space ]. Atlassian may want to consider this an opt-in feature before rolling it out for all customers.

Identify and implement a way to catch future corruptions during save, and log extensive data to help find root cause

Expected Results

Text should be readable and unchanged

It is garbled and missing letters after saving the edit
