"hacked" by the Bulgarian mafia. Or even worse, by Scott & some of his ilk.
Whatever is wrong with the Kiva site today, it is not good.
I'm off today so it's not me!

Seriously though, if I had to make some changes on my site that might be problematic but not show stopping, I'd choose a Saturday or Sunday night to do it and if that wasn't possible, sure, Saturday...
Here's what I suspect is up.. The site has been experiencing record traffic and was dog slow on a Saturday morning... Maybe they said, hey, there are a few simple things we can do to recoup some web server performance (I have one huge suggestion for Kiva below, in this regard) so they went for it a short while ago... The site is performing very snappy for me right now and I can't imagine anyone at Kiva believes that the Team Community thing is at all interesting with the listing the way it is now, so that should change too. Let's give them a few hours to work things out.
As for the suggestion, Kiva, consider chucking out your use of Google Analytics. Use your log files for site stats, they are way way more accurate than crappy Google Analytics which is terribly unreliable and loses stats like crazy because not every request to your site = a successful request to the Google Analytics site - it's a poor solution for tracking stats and Google is also slowing down the user experience for the Kiva.org site as we wait for the Google site to respond to every page we request off of Kiva.org... boo!
Off to Infant CPR class!
