Announcements from AWS [Oct. 26th update] "We are currently experiencing elevated rate of email throttles to Deutsche Telekom email recipients. This is caused by a change in Deutsche Telekom email receiving behaviour. Some customers experiencing throttles may experience a bounced email after the email sending retry period expires. The throttles are impacting a subset of the SES shared and dedicated IP address space across all SES regions. We are actively engaged with Deutsche Telekom to seek resolution of the throttling behaviour. To help expedite this, our recommendation is for impacted senders to have their recipients contact Deutsche Telekom for resolution."
This incident affected: AWS region eu-central-1 (GERMANY) (AWS ses-eu-central-1), AWS region us-west-2 (US) (AWS ses-us-west-2), and AWS region eu-west-1 (IRELAND) (AWS ses-eu-west-1).
