I logged into my Origin PC client roughly an hour ago and received the message that code redemptions were down. My Origin client updated, and then I went and purchased the Humblebundle and decided to try to redeem the codes via my PC Origin client (not via the Origin website) just to see if the servers were still down and all of my codes were redeemed and showed up in my game library.
So go redeem your codes now ladies and gentlemen.
What a joke. The reason Origin doesn't have adequate server power to facilitate the Humble Bundle is because it hasn't needed it. Origin is pretty much useless 99 percent of the time. Saying that your "top agents" are working on is cold comfort coming from the company that ruined The Old Republic and also released Sim City. Please get your act together EA, maybe then you wouldn't be the butt of every joke. My games are installed and working on Steam (the better online platform.)
