Full recovery from 'largest IT outage in history' could take weeks, experts share grim warning

After an IT failure wreaked havoc around the globe, many experts believe that full recovery of the issue could take weeks. On Friday, services began to come back online by evening, however, the problem that led to the outage wasn't completely solved.

What is touted as the "largest IT outage in history", affected airports, healthcare services and businesses. Flights and hospital appointments were either cancelled or the operations were done manually after a botched software upgrade hit Microsoft’s Windows operating system.

The problematic update came from the US cybersecurity company CrowdStrike and the issue left people around the world facing a “blue screen of death”. Shortly after the news broke out, many experts claimed that every affected PC may have to be fixed manually. However, most of the Microsoft services started to recover by Friday evening.

The outage raised many concerns

While explaining the aftermath of the outage, many experts said that the whole ordeal underscored concerns that many organizations were not well prepared to implement a solid contingency plan, The Guardian reported.

They also gave a grim warning that these outages will happen again until more contingencies are built into networks and organizations introduce better back-ups. In the United Kingdom, Whitehall crisis officials conducted a meeting of the Cobra Committee.

Meanwhile, the country's Transport Secretary Louise Haigh, said she was working “at pace with industry” after trains and flights were affected.

"Many people are being affected by today's IT outages impacting services across the country and globally," UK MP Pat McFadden wrote on X, formally known as Twitter.

"Ministers are working with their sectors and respective industries on the issue. "Many people are being affected by today's IT outages impacting services across the country and globally. Ministers are working with their sectors and respective industries on the issue."

"I am in close contact with teams coordinating our response through the COBR response system" he added.

Microsoft bears the brunt

Amid the growing concerns, a Microsoft spokesperson said on Friday: “We’re aware of an issue affecting Windows devices due to an update from a third-party software platform. We anticipate a resolution is forthcoming.

Meanwhile, Texas-based CrowdStrike's founder George Kurtz, said he was “deeply sorry for the impact that we’ve caused to customers”, adding there had been a “negative interaction” between the update and Microsoft’s operating system. In a ripple effect to the whole ordeal, CrowdStrike's stock price fell dramatically, dropping as much as 13 per cent at some point of the trading day.

While commenting on the matter, Tory Hunt, one of the leading cyber experts said that such kind of outage is unprecedented. “I don’t think it’s too early to call it: this will be the largest IT outage in history,” he tweeted.

“This is basically what we were all worried about with Y2K, except it’s happened this time,” he added. Hunt was referring to the millennium bug that worried IT experts in the run-up to the year 2000 – but ultimately did not cause serious damage.
