We were seeing around 450 active users on the site at the peak. We currently have around 220 active users that are generating about two page views per second, peaking to six page views per second. That's about where we were when we scaled up from a single t2.medium instance.

Update on this: looking through metrics at the end of the day yesterday, we realized that the WebSocket-induced errors discussed in https://news.ycombinator.com/item?id=12271043 were having a much bigger operational impact than we initially thought. That's been dealt with and had a clear and immediate impact on the service health.

It would be nice to have another day of similarly high traffic to verify it, but I think most of our scaling up yesterday was to handle the WebSocket issue.
