(Reuters) -Facebook Inc blamed a "faulty configuration change" for a nearly six-hour outage on Monday that prevented the company's 3.5 billion users from accessing its social media and messaging services such as WhatsApp, Instagram and Messenger. The company in a late Monday blog post https://engineering.fb.com/2021/10/04/networking-traffic/outage did not specify who executed the configuration change and whether it was planned. "We want to make clear at this time we believe the root cause of this outage was a faulty configuration change," Facebook said in the blog. The Facebook outage is the largest ever tracked by web monitoring group Downdetector. "Facebook basically locked its keys in its car," tweeted Jonathan Zittrain, director of Harvard's Berkman Klein Center for Internet & Society.
