Facebook's Daylong malfunction is a reminder of the internet's agility



SAN FRANCISCO – Facebook said Thursday that it had repaired a technical failure that led to long-term operational failures on its various features, including Instagram, WhatsApp and Messenger.

The interruption lasts almost 24 hours on some of the services and was the longest in Facebook's latest story. It was an eye-opening reminder that even the most powerful internet companies, using the best computer science and technology, can still be degraded by human error.

"All the major online companies have several lines of defense, but sometimes an encoding error made by an engineer can recover on thousands of computers and cause big mistakes," said Alex Stamos, a former chief security officer on Facebook and a lecturer at Stanford University. In other words, restarting something as complex as Facebook is very, very hard. "

A" server configuration change "made on Wednesday had a cascading effect through the company's network, a Facebook spokesman said. repetitive loop with problems that continued to grow and could not be immediately resolved, according to a current and a former Facebook employee, who spoke on condition of anonymity because they were not allowed to talk to journalists.

The little mistake had major consequences . Instagram users could not see other profiles, WhatsApp users could not send messages, and news streams across Facebook's main app ran out. [1 9659002] Downdetector, similar to itself in a weather forecast for the internet, said it had received 7.5 million problem reports on Facebook apps. By comparison, widespread problems on YouTube in October challenged only 2.7 million reports. Downdetector partly measures service interruptions by counting reports from users who have problems.

"Never before have we seen such a big outbreak," said Tom Sanders, co-founder of the Downdetector.

Early Thursday, Facebook was able to pull most of their systems back online. The company is still trying to figure out how that error reverberated throughout the network. Facebook officials stressed that the problem had not been caused by hacking or a cyber-assault as a so-called "denial-of-service" attack, which would turn servers with a wave of traffic that led them to stop working.

For many years, Facebook has recruited engineers on the idea that within a few weeks they can release the data code that affects billions of people.

Kieley Taylor, global social manager at the advertising agency GroupM, said that the company h ennes had not been able to access Facebook's system, which entails new advertising campaigns were delayed.

"It's never a good day for a mistake," she said. "Fortunately, it was relatively short, but it was completely out."

Her company continued to try to determine how many ad campaigns it had hit. Ms. Taylor said that because Facebook's advertising system worked on a pay-as-you-go basis, GroupM would not need to seek Facebook refunds for non-delivered ad campaigns.

GroupM derived advertising to Google search, YouTube and other websites, but said Facebook had a unique reach given its size.

"Because of all the people on the platform, it continues to be a truly powerful digital marketing platform," said Ms Taylor.
