“The underlying cause of this outage also impacted many of the internal tools and systems we use in our day-to-day operations, complicating our attempts to diagnose and resolve the problem quickly.

“Our engineering teams have learned that configuration changes on the backbone routers that coordinate network traffic between our data centres caused issues that interrupted this communication.

“Our services are now back online, and we’re actively working to return them to regular operations fully. We want to make clear at this time; we believe the root cause of this outage was a faulty configuration change. We also have no evidence that user data was compromised as a result of this downtime.

“People and businesses around the world rely on us every day to stay connected. We understand the impact outages like these have on people’s lives and our responsibility to keep people informed about disruptions to our services.

“We apologise to all those affected, and we’re working to understand more about what happened today so we can continue to make our infrastructure more resilient.”
