Connectivity issues affecting some instances

12:53 PM PST We are investigating connectivity issues affecting some instances in the US-EAST-1 Region.

1:07 PM PST We can confirm Aurora Postgres customers are experiencing intermittent issues accessing their databases in the US-EAST-1 Region. While we have identified the source of the issues, we do not have the root cause identified at this time.

1:44 PM PST We'd like to provide some additional information about this issue. The underlying issue that caused impact to some Amazon Aurora PostgreSQL databases has been mitigated, and all affected customer databases have either recovered, or are in the process of recovering. This issue was caused by an impairment to an Aurora sub-system, which is used by a subset of customer databases in the US-EAST-1 Region. The impact of this issue was limited to a subset of Amazon Aurora PostgreSQL databases in the US-EAST-1 Region. Non-Aurora databases and Amazon Aurora MySQL databases were not impacted. We are actively monitoring this sub-system while we work in parallel to ensure all customer databases are fully recovered. We will provide another update within 30 minutes.

2:19 PM PST We have an additional update about the issue impacting some Amazon Aurora PostgreSQL customers in the US-EAST-1 Region. The vast majority of impacted customer databases have recovered and we are in the process of mitigating the remaining impacted databases. We will provide another update by 2:45 PM PST.

2:46 PM PST We have an update on the issue impacting some Amazon Aurora PostgreSQL customers in the US-EAST-1 Region. We are continuing to work towards mitigating the remaining customer databases. We will provide another update by 3:45 PM PST.
