We’re offline for an urgent security update.
This is not routine maintenance.
A serious security flaw has just been announced in PHP, the software behind most of the world’s websites. Cyber security agencies advised taking websites offline until the fix was in place. In the US, that advice came from the National Security Agency.
Sites around the world have gone offline, including parts of Wikipedia and government websites in Australia and Europe. We did the same, as a precaution.
Your account and progress are safe.
We’re installing the fix now. We’ll be back as soon as it’s tested.
