I think you should increase your check time to at least 4 seconds. My rig randomly shows offline on the site but it never is actually offline, and with the changes I've made there's no more drops pinging the internet, so I'm not sure what's going on, but it's not on my end anymore. I'm sure it takes longer than 2 seconds to run through a ping check of 100+ machines from your side.

Also, I'm confused on the displayed price that shows in the rig list. My best price listed is .0198, but I put in .022 on the admin page, and it's .02146 after your cut, so is that .0198 actually correct?
