An excerpt from a Sony reality check; tangentially, also see Sony’s missteps through the years
Now let’s consider for a moment why this outage is continuing a week after the break-in. Speaking with a few experts and reading the official Sony FAQ gives some insight into what may really be going on. Sony says it is investigating, but should an investigation really take this long? Can’t the server logs and other network data be locked-down in a few minutes and examined at leisure? Sure. So when Sony says it is investigating what they probably mean is they are trying to fix the problem, seal the breach, and make sure that particular gambit cannot be accomplished again. This takes time — hours of programmer time and dozens or even hundreds of hours of QA time to make sure the fix scales properly and will work under a full network load.
Sony doesn’t say this, of course, but that puts us back to the fierce pride part. While they can admit a break-in they find it very difficult to say they are putting locks on the doors that never had them.
