Why did they blur the information when there are pretty advanced de-blurring algorithms out there? Seems like if you want to redact the information you need to completely omit the subsequent pixels rather than just adding a blur effect. Perhaps since the issue is fully resolved and I would guess that AWS rotated everyone's credentials?
