Sonar Review Alpha bot no longer works? Says "is currently unavailable"

Hi,

Thank you for your kind words about the Code Review Alpha. I’m sorry it came as a surprise that we were retiring the Alpha. We thought we had contacted everyone who was using it.

Now that Sonar has acquired Gitar that will be our Code Review solution moving forward.

Thank you again for using the Alpha and please let us know how you get on with Gitar.

John
