NGP VAN, the vendor that handles the master file, said the
  incident occurred Wednesday while a patch was being applied to
  the software [via Washington Post] A member of Sander's team
  broke a big rule and the whole team was penalized but I'm
  personally disappointed in the software vendor for not being
  responsible for their actions. I know the type of person who did
  the live-patching of the software: We had them at my
  Schering-Plough job: One day, a guy decided to push an update to
  the latest ODBC drivers to ALL the Windows computers (that's
  thousands and thousands) one morning around 9:30am. Without
  permission. Nobody asked him to do it. n00b Anyway, you just
  don't do that. Enthusiastic patching is dangerous in corporate
  environments. My programs couldn't run as they depended on those
  drivers being a particular version. I wasn't alone. It was
  crippling as "fixing the fix" took a good three weeks. [pushing
  the old version back wasn't going to work because all of the
  computers had slightly different versions] He got canned too and
  other people had to clean up his mess. Upgrade-itis without
  seeing the consequences. I could give a dozen other examples.
  I'm disappointed in the software vendor myself.
