To summarise that post, it brought me about 95000 hits on the first day. That was a simple, static, standalone HTML page and the traffic was way below what Nginx can handle without breaking a sweat, so never had any trouble on the web server.
30000 visitors per day is 20 per minute.
With stats like that, break out an AWS XL and ensure your Lambdas are ready.

Would suspect that number is much, much higher now.
