Our 15k/month account did not get such an email when they introduced the dc2 redshift class, despite most of our spend being on Redshift.

I'm consistently surprised at how big the variance in quality of service is from different AWS account managers; seemingly regardless of the size of account.

The 2/3 reps we've had have been night and day in the level of service they've given us, and we're a top 10% customer by volume.

Recommend checking who the account emails are configured to be sent to. Often they go to a finance person who may not understand the importance of some communications such as this.

AWS probably want the old less power efficient gear out of their DCs as soon as possible.
