Root Cause
Email from Martin at 8.50 on Monday 23/01/17:
There were errors during the refresh process for the Intrepid Data Repository on 18/01/2017 at 15:33
The Data Repository was restored from the latest successful run on the night of 21/01/2017, and therefore data is now over 24 hours old.
We expect resumption of normal service, and a successful refresh to occur tonight. Further communication will follow if this changes.
Given that minimal changes will have occurred on a Sunday, we do not anticipate an issue for the majority of DR users. However extracts taken overnight will be incomplete, and therefore we would advise re-running these extracts.
Note that we had to kill active sessions for users logged in at the point of the restore.
Please accept our apologies for any inconvenience caused.
Thanks,
Martin
