Not sure if its related or not (I'll just assume it is), but dockerhub is down as well. Haven't been able to push or pull for the last 15 minutes, some other folks complaining of the same thing.
Yea my self hosted concourse is down. Feels quite bizarre to have our internal CI so crippled by S3... though i'm still investigating, perhaps the workers are just hung after all of the failed docker pulls.
