Facebook confirmed networking issues on all its properties on Monday. Aside from messenger, the massive outage took down Instagram, WhatsApp and Oculus.

With that, Facebook users flooded Twitter to post their memes and reactions on the offline services.

The Facebook outage started just before noon ET and was fixed some time at 6:00 PM ET. The almost six hours of offline service is the second-worst outage for Facebook, with the first being its 2019 incident that took more than 24 hours to fix.

Both Down Detector and Twitter newsfeeds highlighted the Facebook outage problems that happened worldwide, regardless of server or language. The outage unfortunately blocked a lot of functions from its extension websites, too.

According to The Verge, the Facebook outage broke nearly all the company's internal systems used by employees for work. Some FB employees resorted to their Outlook email accounts as a communication platform. Employees who were already logged in to their Google Docs and Zoom could still use their accounts, but employees with logged out accounts found their work email blocked in the outage.

During the outage period, Instagram servers flashed "5xx Server Error" messages. Facebook's virtual reality arm, Oculus, also experienced issues. Users could load pre-installed games and online browser, but accessing social features and installing new games were impossible to do.

Facebook communications executive Andy Stone said Facebook was aware of the problem and they were working on the issue.

Mike Schroepfer, the chief technology officer of Facebook, said networking issues caused the outage.
