> We actually created this as an internal tool because there wasn't anything that would give you a clear indication of site performance from DNS lookup to connect to TTFB to page render from around the world.

Out of curiosity, did you look into any paid services like SpeedCurve or Calibre? There are also OSS projects like SiteSpeed or WebPageTest.

Full disclosure: I work at SpeedCurve. We've had customers cancel their accounts in the past because they wanted to build their own performance monitoring tool. To the best of my knowledge, most of those customers have come back because building and maintaining a tool like that is no easy task.

...Which I guess is a strange way of saying congratulations on building a performance monitoring tool!
