We've been looking into the reports of gateway timeouts and although we are seeing only a limited number of them, the few we are seeing is more than we are happy with.
Our internal statistics are showing near-zero gateway timeouts, but our CDN partner is showing some. It's still a small number, but as I said, it's not something we are happy with. As part of our investigation into the issue we will be stress testing various parts of our infrastructure this evening. The stress testing itself should not be causing any downtime, but if configuration changes are required, there might be a few minutes of downtime.
