Redshift backend maintenance on September 24th

Due to a bug in AWS Redshift that we're unable to resolve without service interruption we're announcing system wide Redshift backend maintenance on September 24th.

The bug shows increased table sizes. If you're experiencing unexpected project size growth you might be affected by this bug.

During the maintenance all data on Redshift backend in affected projects will be unavailable and all Redshift transformations will not be able to execute. The maintenance will last around 3 hours. 

The schedule of the maintenance in different timezones is following:

PDT: Saturday, 24 September 2016, 05:00:00-08:00:00
UTC: Saturday, 24 September 2016, 12:00:00-15:00:00
CEST: Saturday, 24 September 2016, 14:00:00-17:00:00

If you're concerned about the maintenance or you need to schedule a different time please contact us at

Update September 16th: The maintenance is cancelled. We're working on an on the fly detect-and-fix solution. Release date unknown yet, so if your project shows any growing table size symptoms, contact us at to help you fix the problem.
