We're on it. It pulled our piefed instance down too. And of course it happened in the middle of flooding (IRL flooding)!

they either have disk space issues, or they have implemented temporary restrictions in their PHP settings due to the recent world-wide security issues.

if you cant patch, the solution was to disable multi-part forms which breaks 'big' uploads.

Not sure if its related but I'm unable to upload images but I'm getting a timeout error.
