The access problems this morning, which started around 11.02 and lasted just over an hour, were caused by one of our databases failing. In order to resolve the problem we removed the problem database from our configuration.
The team are now working on getting the problem database back in to an operational state at which point we will focus all efforts on investigating what triggered the database failure.
We will leave this incident in "monitoring" for the time being and ensure that a post mortem is completed once everything is back up and running as normal.
Sorry again for the problems this morning. We know how frustrating this will have been to all users.
