>12:54 PM PDT We have resolved the issue affecting Internet connectivity to a single Availability Zone (USGW-AZ3) in the US-GOV-WEST-1 Region. The issue has been resolved and the service is operating normally.
As far as I can tell from some of my automation, the outage started between 1 and 1:15pm Eastern and the outage was "fixed" between 3:15 and 3:30 pm.
I say "fixed" because we're still seeing lots of slowness in the API responses.
