My last successful build was at 13:39
back at 20:30, now builds are failing. The only available clue is that
the error logs of failed builds all end with

Now, the plot thickens. As I started composing this message, I also started
another build, intending to wait until it also failed to hit send. This
turned out to be unnecessary, since the third build magically came back from the
dead and became a successful build. See the attached screen shot.
