User data loss for Jupyter Notebook service 21/02/2023
During some routine maintenance on Tuesday 21st Feb 2023, we encountered data loss of users volumes on the Jupyter Notebook service.
The issue was caused by a mix of operator error and a bug in the underlying storage component of the service.
We have explored options for data recovery, but we have concluded that it is technically unfeasible.
We have written a blog post which explains the technical situation we encountered, for those who might be interested.
We sincerely apologise for any inconvenience this might have caused.
