The Pingdom report (http://stats.pingdom.com/x8mbe1jgimkn/49229) shows a consistent response time of about 0.6 seconds all day almost every day.

As a first step in tracking this down, I would suggest you try the command 'TRACERT www.fastmail.fm' and see if there is an obvious performance bottleneck on one of he hops between you and FM. If you are using Windows, it may also be of value to run the diagnostic program FastTest (download link) and see if this can identify the source of the problem. Sometimes, it is something as simple as the network routing tables used by your ISP.
Thank you. Indeed, it looks pretty messed up to me: the second hop out from my router is a timeout:

TRACERT www.fastmail.fm

Tracing route to www.fastmail.fm [66.111.4.56]
over a maximum of 30 hops:

What do I do now?
