Hi, came along that tweet: https://twitter.com/tobiasfrech/status/678858126414716928 Suppose this happens and we did record that the update was end of week 48 we could in an alert not only say "value X too high" [1] but also deduct that this is most likely due to the update. [1] Currently this depends on having an alert trigger correctly defined to alert if the value goes above the max of week 45..48. We may want to have alerts figure this out automatically via the data analysis from Pavol.
