An explanation of a similar occurence:

They went down in a similar fashion in '06. Here was their explanation for that.

"We were taking the low-load Saturday as an opportunity to perform some maintenance on the storage system, specifically on some very large (>100 million objects) buckets in order to obtain better load-balancing characteristics. Normally this procedure is entirely transparent to users and bucket owners. In this case, the re-balancing caused an internal transit link to become flooded, this cascaded into other network problems, and the system was made unavailable. We are taking several steps to ensure that we don't run into this situation again. We are modifying our maintenance procedures, and are adding further monitoring to prevent the transit link from getting full. In addition we are modifying the way that our system makes use of the network to prevent the cascading effect we saw on Saturday. Providing world-class reliability is our top priority for Amazon S3. We appreciate your patience, and hope to surpass your expectations going forward."

I don't think I'm a robot, but maybe that's one sign of actually being one. :shocked:

I got the same thing. my wife looked at the screen and nodded in approval, exclaiming how it's interesting that amazon.com knows how I act in bed.

The PS3 fanboys honestly believe they killed Amazon? There have been FAR bigger promotions that Amazon has survived just fine, generally without as much as a slowdown.

Well what is interesting about this is the 503 return code came back almost immediately. I was a geek and took a trace to see what was going on. The 503 came back at 20-50 ms.

This means it's the load balancers/content switches sending that return code. So I would guess somehow, someway the balancers ran out of flow resources which would be indicative of a layer7 based DoS (could be L4, but highly doubtful). Given that HTTPS seemed to still be up only confirms it. Couple this with some users now getting a sorry server page (you're flagged as an unusual flow, amazon errored on the side of keeping the bad flows out at the risk of harming legitimate ones). It all makes sense. No 302 return code, which means all balancers were out of resources.

What is even more interesting is looking at the trace a L4 reset was not sent after the L7 503 return code. That is unusual to say the least in that the socket to the load balancers was not closed, which would reaffirm a lack of resources filled by junk sessions.
