All customer SDDC environments in Availability Zone use1-az4 within the US-EAST-1 Region are now fully functional and operating within SLO.

AWS have implemented a fix for the impairment in Availability Zone use1-az4 within the US-EAST-1 Region. AWS are gradually bringing systems online, rack-by-rack. All EC2 and EBS systems are expected to return to normal status within 24 hours.
