Meta communications boss Andy Stone shared on Facebook and X regarding the outage earlier this month - but it has been crickets about Wednesday's incident.

Issue reports submitted by users to DownDetector showed there were more problems with Facebook, followed by Messenger and then Instagram.

More than 60 percent of reports noted for all three cited the apps were not working properly - 67 percent for Facebook, 61 percent for Messenger and Instagram's app sits at 66 percent.

On Facebook, users were seeing notifications that their accounts have been suspended or their session had expired and are asked to login again.

Messenger's issues were showing users as being 'unavailable to friends.'

While some people had said they could send messengers, but recipients were unable to reply. 

And Instagram users were reporting issues with comments, messaging and News Feed.

'Is Facebook really down again ? Or is it just me,' one user posted on X. 

While another Instagram users asked: 'Can't able to load feed, comments, chat since morning! Is anyone facing the same issue?'

Both #Facebookdown and #Instgramdown were trending on X, sparking a flood of what appears to be scammers claiming they can help people regain access to their social media accounts.

Wednesday's outage brought up memories of the one that hit on March 5, which seemed to spark chaos online worldwide. 

While it lasted for no more than two hours, users were outraged by not being able to access the three social media platforms.

 Facebook's seven-hour blackout that cost the company an estimated $100million in lost revenue alone was made worse because staff were working from home, an insider has claimed.

A source inside Facebook told DailyMail.com that the company's internal systems were also down, which may have led to the issues - it is unclear if similar problems sparked today's outage.

The majority of issue reports also cited problems with the apps – 72 percent for Facebook, 64 percent for Instagram and Messenger is at 50 percent. 

Meta's service dashboard, which lists its services, continued to show major disruptions for some features – but then switched to 'Unknown' for all or completely blank. 

While reason for both outages have remained unclear, it comes three years after Facebook experienced a seven-hour blackout that cost the company an estimated $100million in lost revenue.

The global outage – which hit Facebook, Instagram, WhatsApp and Messenger – was caused when a faulty update that disconnected its servers from the internet, meaning engineers had to travel to its Santa Clara data center to fix the glitch in-person.

But the repair was delayed, according to one insider who was posting on Reddit, because of 'lower staffing in data centers due to pandemic measures'.

The glitch, which prompted calls for a break-up of big tech firms, also brought down messaging services that remote-working staff use to communicate.

So those who knew how to fix the servers couldn't get that information to the teams inside the data-center, the insider said.

Also disabled were key-fob entry systems at Facebook's main campus in Menlo, meaning those who had been WFH but rushed back to the office could not get inside while those already inside were unable to access conference rooms and other areas that required a pass.
