Impact | Revalidation application was functionally unavailable |
A process which refreshes all of the data in the revalidation system was triggered accidentally on the production (“live”) environment - the intention was that it was only to be run on the staging (“testing”) environment. Once this process has started, it must be allowed to complete for data to be restored, and unfortunately it takes a very long time to complete.
Accidental triggering of full production data sync
Noticed by developer
Allowed process to complete naturally
All times in GMT unless indicated
14:45 Sync process accidentally triggered
14:45 Impact on production environment noticed by developer
16:41 Failure in last stage of process noticed
16:50 Cause of failure identified
16:57 Failure rectified, process resumed
20:33 Process completed, system restored
23:18 Recommendations Bug Discovered
07:15 Users notified on Teams of Recommendation issues

Why did the connections list disappear on production
An unscheduled full production data-resynchronisation was triggered
Why was an unscheduled full production data-resynchronisation triggered?
Human Error
“preprod” and “prod” are not visually distinct enough?
Why was the sync not terminated?
No way of aborting the job or quickly reverting
Why did the recommendations list disappear?
Because the DTO naming conversion (“traineeInfo” → “recommendationInfo”) in the integration service stopped working
Why did the DTO naming conversion in the integration service stop working?
This commit solved the datetime issue, but appeared to change the JSON mapping in the application, particularly for REST documentation, in such away that it didn’t play well with Camel
Action Items | Owner | |
|---|---|---|
Fix the JSON mapping issue in recommendations, and revert any patchwork done in the FE to compensate | Done | |
Automated backups or similar “built-in” to the sync process so that it can be aborted and restored as required |
| |
Introduce batch messaging to speed up biggest bottleneck - judging by the work on the overnight doctor sync this could reduce the whole process down to a couple of hours | Already have work lined up in addressing the raised action e.g GMC sync work |
Mistakes happen
