A list of known issues with data in Advanced MIS with a short explanation of the circumstances. Listed with most recent errata at the top.
June 2025
All events - 16th June 2025 at approx 13:00
On the 16th June 2025 between 13:00 and 14:00 UTC, an issue occurred which resulted in Advanced MIS event processing being paused for a number of days. We were able to recover data from backups. There is a small chance that for a period of one hour some events are either duplicated or lost. Unfortunately we have no way to accurately measure this. We estimate that the discrepancy will be small for just that one hour.

Reading List Events from 18th November to 30th November 2022
List view and interaction events were not captured for a period of 12 days between 18th and 30th November 2022 inclusive. This will apply to events like list.entry_point and list.item.click. This means that student and staff clicks on a list and edit actions will not have been counted. An investigation has concluded that it is not possible to recreate events for this period.
The list of affected events are as follows:
list.entry_pointlist.item.clicklist.item.external_link.clicklist.editlist.item.report_broken_linklist.item.cancel_report_broken_link
All other list functions continued to work as normal and all edits to lists will have completed as expected.
