"Digital services have to be built to perform perfectly every time, or customers are going to get hacked off pretty quickly," Michael Allen, solutions VP for web performance management firm Dynatrace, said.

People manage to do their shopping, banking and book their holidays online. They are not prepared to excuse poor performance on government websites.
It's time for the DVLA to do a serious investigation into why its website has failed to meet demand, twice, and take action to fix it.
