You can match them up through a quirk in one of the APIs.

My us-east-1a is the affected zone, which is 3a98bf7d-126d-411a-a612-3a57a62dc688 using the incantation on the site.

(Oh, and to note: my us-east-1a was also the affected zone during the massive outage last year, and I believe I remember another outage sometime between then and now. I almost feel like every Amazon outage affects my zone. I kind of wonder if that availability zone just sucks ;P.)
