Facebook and Instagram on Sunday experienced widespread outages for the second time within the past month.
The websites for both social media companies were inaccessible to users worldwide, and the news feeds on their apps were not refreshing, The Verge reported.
The issues began around 6:30 a.m. on Sunday, according to multiple reports, and service was restored at approximately 9 a.m.
Facebook, which is the parent company of Instagram, did not immediately return a request for comment.
Facebook and Instagram each experienced outages last month, when the sites were down for more than 24 hours in the longest outage in their history.
Facebook later attributed the outage to "a server configuration change."
"Yesterday, as a result of a server configuration change, many people had trouble accessing our apps and services. We've now resolved the issues and our systems are recovering. We’re very sorry for the inconvenience and appreciate everyone’s patience," the company said in a tweet at the time.
