Upwards of 30 seconds to timing out completely for me :c
Sometimes, rarely, the load averages on the server are greater than 100%. This usually only happens for periods of about 15-20 minutes during some peak times, typically when north america wakes up, and then again when russia wakes up. If load averages continue to climb we'll consider adding more resources to the VPS but right now, we're not breaking even on ad revenue vs. satoshi output so any other costs make it even more difficult to keep the site running, let alone add bigger and better prizes.
EDIT: I checked a few times over the past 15 minutes all the site always loaded, between 5 - 10 seconds.
