I have a cron that writes daily backups to S3 buckets in both us-east-1 and eu-west-1. I was a bit surprised that both buckets were inaccessible during the outage. Now I have it writing to Backblaze B2 instead of eu-west-1. Hopefully that’s completely independent.

> I was a bit surprised that both buckets were inaccessible during the outage. Can you provide more details? I did not observe that. If that was the cause, would that not mean the outage would even more massive, with companies outages across all regions?

  The DNS names- `bucketname.s3.us-east-1.amazonaws.com` and `bucketname2.s3.eu-west-1.amazonaws.com` failed to resolve during the outage.

    Thanks for sharing that. Interesting detail. Do you know if those lookups came from workloads inside us-east-1 ?

      No, I was trying to download from my home internet- Astound in Seattle. I run a local recursive resolver that was unlikely to have those subdomains cached.
