Hmm.. I'm not jumping to conclusions as to why a few of my eCPCs dropped over the last week, but who knows if this could be a small fraction of the reason.
How did you notice that azjmp.com goes down for 2-10 minutes at a time? Do you have a pingtest on there or something? Maybe I should code one up real quick today as a test, run it (via cron) every few minutes, and notify if a 200 isn't returned. Probably should have done this a while ago as a precautionary measure anyway but never really had any reason to.
