Earlier this month, David’s heartfelt posting about leaving Mozilla made the front page of Hacker News. Traffic increased by 800% to his already-busy website, which slowed and eventually failed under the pressure. Request Metrics monitors performance and uptime for David’s blog, and our metrics tell an interesting story. Here’s what happened, why, and what you can do to prepare your site for traffic surges.

David’s site uses WordPress. It serves most content from a MySQL database, which is a well-known performance limitation. To mitigate this, David uses Cloudflare to cache the content of the site and reduce the load to his server.
Cloudflare does this by taking control of DNS and routing requests through their edge network before calling your server. When possible, Cloudflare will return cached content rather than needing to call your server at all, which is particularly useful when request volume goes way up.
