Building APK Gives 0 Byte Download

I've been trying all day to build an APK file to my desktop but the resultant file is always 0 Bytes in size.

This has been working moderately well for months, apart from the odd apk being corrupted in some way (rebuild fixes)

The high usage of AI2 on the 10th/11th resulted in some server errors.  MIT made a 'fix' that should prevent issues in the future, however those projects that got 'corrupted' may require some remedial action on the part of the user.

Do you have an aia file of the project when it last ran successfully?

We will try to help but at the moment do not have  a comprehensive solution for fixing projects that may have issues.   Your comments will help MIT and us figure out a solution.

Did you have lots of images?    If so, the solution may be to delete all the images from your Media and reload them and try to run/compile the project again.   Does that work?

Thanks for the info, yes I keep copious back ups (every time I make a change).

Could I suggest that MIT add a status page to the web-site?

William... The problem is that the servers are actually Google's App Engine servers, of which MIT has no control.  Status in terms of MIT is that everything's fine.  Status on Google's Cloud Servers is nebulous...
