Cybersecurity expert Mike Chapple said “a slow and bumpy recovery process” is “entirely normal.” As engineers roll out fixes across the cloud computing infrastructure, the process could trigger smaller disruptions, he said. “It’s similar to what happens after a large-scale power outage: While a city’s power is coming back online, neighborhoods may see intermittent glitches as crews finish the repairs,” said Chapple, an information technology professor at the University of Notre Dame’s Mendoza College of Business.

While it seemed the worst had been resolved, a new series of “cascading failures” seems to have arisen during the last few hours, according to Mike Chapple, an information technology professor at Notre Dame University. “It’s like when you have a large-scale power outage,” Chapple said. “Crews start working to try to bring it back on line. The power might flicker a few times,” but it’s possible “they’d only addressed the symptoms” and not the root cause.

These outages happen to Amazon infrequently, says Mike Chapple, who teaches cybersecurity at the University of Notre Dame. "Hopefully you never have the same kind of failure happen twice," Chapple says.

“That’s on par with the other major cloud providers and, in fact, it’s amazing that they’re able to run at the scale they do without more frequent disruptions,” said Mike Chapple, a cybersecurity expert and IT professor at the University of Notre Dame’s Mendoza College of Business. “The reason these events attract much more notice is because of their impact,” he told CNN. “If a single company experiences an issue in their data center, it causes issues for that company’s products and services.”

Mike Chapple, IT professor at the University of Notre Dame’s Mendoza College of Business, explains why DynamoDB is important, and why its failure has caused so much disruption today: "DynamoDB isn’t a term that most consumers know, but it underpins the apps and services that all of us use every single day. It’s a centralized database service that many Internet-based services use to track user information, store key data, and manage their operations. DynamoDB is one of the record-keepers of the modern Internet. It’s fast, it’s cheap, and it’s reliable. But today it stopped working and we saw the effects of that outage ripple across the Internet. We’ll learn more in the hours and days ahead but early reports indicate that this wasn’t actually a problem with the database itself. The data appears to be safe. Instead, something went wrong with the records that tell other systems where to find their data. Amazon had the data safely stored, but nobody else could find it for several hours, leaving apps temporarily separated from their data."

Mike Chapple, a cybersecurity expert at the University of Notre Dame, described the disruption as “temporary amnesia” for the internet, noting that while data remained intact, systems couldn’t locate it.

Indeed, “DynamoDB isn’t a term that most consumers know,” Mike Chapple, IT professor at the University of Notre Dame’s Mendoza College of Business and former computer scientist with the National Security Agency, said in a statement. However, it “is one of the record-keepers of the modern Internet.” “We’ll learn more in the hours and days ahead but early reports indicate that this wasn’t actually a problem with the database itself.

Amazon’s DynamoDB is one of the record-keepers of the modern internet, said Mike Chapple, an IT professor at the University of Notre Dame and former computer scientist with the National Security Agency. Chapple said the outage is a reminder of the world’s reliance on major cloud providers such as Amazon, Microsoft and Google. “When a major cloud provider sneezes, the Internet catches a cold,” he said.

Mary Ellen O’Connell, a professor at Notre Dame Law 91视频 and an expert on international law, warned that the administration’s actions appear to violate international legal norms. "Now it appears he has ordered the CIA to violate international law with covert actions in Venezuela,” O’Connell said in a statement to Newsweek. “Lawful law enforcement or military action on the territory of a foreign sovereign state must have the consent of that state,” she added.
