Worldwide tech outage disrupts hospitals, airlines, banks and other industries. Here is the latest

Scale of outage concerns experts

Even as companies and institutions began restoring regular services, experts said the cyber outage revealed the risks of an increasingly online world.

This is a very, very uncomfortable illustration of the fragility of the world’s core internet infrastructure, Ciaran Martin, professor at Oxford University’s Blavatnik School of Government and former head of the U.K. National Cyber Security Centre, told Reuters.

I’m struggling to think of an outage at quite this scale, said Martin.

Ritesh Kotak, cybersecurity and tech analyst, told CBC News Network that clients and consumers will have to be patient.

A lot of these systems have redundancies that are built into them. So, for example, when one system fails, it can piggyback off another system; it just literally passes the baton, said Kotak.

It’s not as smooth sometimes as one may think … but depending on the scale of the servers impacted sometimes it takes just a little bit of time to pass over that baton and then fix the problem and then bring those services back on to the original servers.

The outage created challenges for some doctors and hospitals in Canada and internationally.

We are aware of the IT outage and the challenges it is creating for health-care professionals and hospitals. We are actively monitoring the situation and working with partners across Canada to support our health infrastructure, Health Minister Mark Holland said in a statement.

Several airlines affected

Airline traffic was especially affected, though the impacts were variable. A spokesperson from Toronto’s Pearson Airport told CBC News the impacts varied airline to airline.

As of now, Air Canada, Westjet, Sunwing and Flair operations have not been affected. We’re still seeing issues with major American airlines (Delta, American, United) as well as Porter Airlines, Pearson said in a separate statement.

Porter Airlines, which operates flights across Canada and to some U.S. locations, said all flights would be cancelled until at least 3 p.m. on Friday. The company said just after 6 a.m. that its call centre agents did not have access to reservation or rebooking information, and it’s directing customers to its website for updates.

Any passengers needing to cancel travel plans as a direct result of the systems issue will be offered refunds, said Porter. Normal flight change fees are also being waived.

Out of over 110,000 scheduled commercial flights on Friday, 2,691 have been cancelled globally so far and more are expected to be called off, according to data from global aviation analytics firm Cirium.

Representatives from the international airports in Montreal and Vancouver told CBC News that U.S. customs officials could not process passengers heading to American destinations. U.S. Customs and Border Protection released its own statement indicating the issue, related to the global CrowdStrike outage, had been resolved.

Montreal-Trudeau International Airport said the problem has been resolved and passenger processing is gradually resuming. 

Airports across Canada have advised customers travelling or doing pickups of family and friends to check flight status with the airlines before heading out.

Traffic delays at points of entry on land between Canada and the U.S. were also reported.

The Canada Border Services Agency (CBSA) said in a statement that it had experienced a partial systems outage of its telephone reporting system that was subsequently resolved. The statement did not make reference to CrowdStrike and Microsoft issues.

In the U.S., the Federal Aviation Administration said the airlines United, American, Delta and Allegiant had all been grounded for an extended time span.

Internationally, airports from Britain to India and Hong Kong reported delays, with some resorting to manual check-ins. Ryanair and Air India were among the airlines most impacted.

French airports said the issues were airline-specific and the Paris Olympics organizing committee said on Friday the impact of the global outage on its operations was limited and ticket sales were unaffected ahead of the Summer Games, to begin in one week.

Private, public sector issues

CrowdStrike says it has more than 20,000 subscription customers around the world, with over half of Fortune 500 companies using its software, according to company promotional materials from this year.

As a result, a number of companies across sectors were affected.

FedEx Corp said on Friday it experienced substantial disruptions to deliveries throughout its networks.

Contingency plans have been activated to mitigate impacts but potential delays are possible for package deliveries with a delivery commitment of July 19, FedEx said.

The CBC experienced some issues with automated broadcasting processes, affecting control room operations, cameras and graphics, that were resolved after a few hours.
