Here's how things usually work: Have a major outage, then fire your operations guy. At Marc Andreessen's Ning, the social-network Web host best known for its porn sites, things run a bit differently. On Monday, CEO Gina Bianchini fired VP of operations Alexei Rodriguez. On Wednesday, the company saw all of Ning's networks go offline. We hear Rodriguez failed to deliver a promised upgrade to Ning's systems that would have avoided the problem; the outage was coincidental but almost inevitable, given Rodriguez's omission. The larger problem for Ning: No one seems to care that it was down. When you offer porn and still no one complains that they can't get to it, you have a problem which goes much deeper than database configurations.
