Some of the world's biggest websites and apps stopped working for many but not all visitors on Wednesday.
Several of Facebook’s products suffered partial outages, affecting users globally.
Facebook plus its Messenger service, Instagram, WhatsApp were all disrupted with log in or posting problems.
The cause of the interruption is not yet known but Facebook have stated that it is not a result of a DDOS attack (Distributed Denial Of Service) a type of cyber attack in which a company's network is flooded with requests potentially causing it to fail.
In a statement on Wednesday afternoon Facebook said: "We’re aware that some people are currently having trouble accessing the Facebook family of apps. We’re working to resolve the issue as soon as possible”.
The last time Facebook had a major disruption was over eleven years ago in 2008 - the site had a mere 150million monthly users then - compared to around 2.3billion monthly users today.
Visitors to the US Postal Service and Etsy websites also reported having problems starting at roughly the same time.
Problems seem to have started appearing around 4pm GMT and at this stage it is not clear whether the various outages and disruption are connected.
Reports suggest that the problems have been resolved for some users but as at the time of writing problems are still being reported - we are still unable to log in directly to the NewsInCyprus Facebook page.
Update: We were finally able to access our Facebook page around 12:30 am but shortly after the problems reappeared and we were again unable to log in.
