Thus, Troy Hunt, a cybersecurity consultant, wrote in his account of X that the magnitude of the computer failure was unprecedented. “I don’t think it’s too early to say: it will be the biggest computer blackout in history“, he said.

Meanwhile, Adam Leon Smith, an employee of the BCS, a British institution responsible for analyzing advances in information technology, he claimed The Guardian said it could take days or even weeks for systems to recover.

According to the expert, “in some cases, the fix can be applied very quickly,” but “if computers reacted in a way that means they are entering blue screens and endless loops, it can be difficult to restore and could take days and weeks“.

Alan Woodward, professor of cybersecurity at the University of Surrey (United Kingdom), said that recovering the systems requires a manual reboot of the affected machines and that “most standard users would not know how to follow the instructions.” “For some organizations, it could certainly take weeks.”he added.
