We are aware of intermittent login issues that might affect customers. We apologise for the trouble, and we are working on fixing it.
Fingers crossed, this may be fixed! We will see how it develops tomorrow.
We apologise but we are still experiencing intermittent issues, although we have managed to slow down the frequency. We continue working as hard as possible to find a permanent solution. The main symptom is that you will be unable to log in. The failure should only last 2 - 3 minutes, after which you can try again. We apologise for the trouble.
