WE are heavy users of AWS. SQS is the only service where we have had zero downtime. The only downside we have about SQS is you can pull out only 10 messages at a time (without batching). You can have parallel readers but they result in some duplicates. There is SQS FIFO but it is throttled.

It went down on us once for extended period in 2015. It was chaotic as you don't expect it to fail. If memory serves me right, even S3 suffered that day.
