How are you measuring traffic to your website? If you're using a
Javascript-based tool (like Google Analytics), then it won't be a fair
reflection of the load on your servers. Is it possible something (crawler,
botnet, scraper) is hitting your website and increasing the load, but not
loading the analytics scripts? Are you measuring messages entering Storm?
