Starting at approximately 1:15 PM today, several of our customers started experiencing intermittent errors with Kiln where they were getting 500 errors on push and/or getting "Kiln has overheated" errors when using the Kiln UI. The problem was caused by one of our web servers. That particular web server has been taken out of the pool and it looks like the problem has gone away. We are going to continue to look in to what caused the server to fail and how we can prevent this problem from occurring again in the future.
