Bureaucracy is almost always the reason. They don't just need a website, they need -their- website back, because it was programmed with a million little business rules and pricing logic and regulatory requirements.
That would also take a lot of the pressure off of the "full recovery team."
Of course, the real situation must be 100x more complex than I'm imagining it so "I'd like to think" != "I am confident"
The real situation is not 100x more complex, it's just that this is happening in Britain where everything is someone else's job and no one has any reason to care about the actual goals and everyone will go home at 5pm. Or, more likely, to the pub.
