Most likely the job that uploads this stuff at databricks is broken.

Hi,

I was trying to look at some flaky tests and old jiras, and noticed that spark-tests.appspot.com is still live, but hasn't updated with any builds from the last 2 months.  I was curious what the status is -- intentionally deprecated?  just needs a restart?  more dev work required?

its pretty handy for dealing with flaky tests, could help get it up again if its something small.

thanks,
Imran
