Database updates are back online!
Commons uses an on-device database cache to store information that does not change very often, such as the career history of MPs. This database is usually updated automatically when its content is updated, but the server which handles these updates recently suffered a hardware failure. This resulted in the on-device database falling out of date.
I am happy to announce that the server is now back up and running, and that measures have been taken to minimise the impact of any similar failure in the future. You can now expect the cached database to update within a few days of any data changes being detected.
