Facebook services go down again Friday afternoon

SAN FRANCISCO - Facebook services went down again on Friday afternoon after one of the longest outage ever in the company's history on Monday.

"We're aware that some people are having trouble accessing our apps and products," the company tweeted. "We're working to get things back to normal as quickly as possible and we apologize for any inconvenience."

Meanwhile, Instagram also tweeted, "We know some of you may be having some issues using Instagram right now. We're so sorry and are working as quickly as possible to fix."

"The repeated lapse might spark concerns about the reliability and safety of the app," TechCrunch, an online publisher of technology industry news, said in a report.

Friday's outage was due to configuration changes, which impacted people globally, but it was unrelated to Monday's downtime, according to TechCrunch.

Monday's outage, which affected all Facebook services, including WhatsApp, Messenger and Instagram, was caused by configuration changes to the routers in Facebook's data centers.
