Social media site Facebook crashed worldwide this evening, but was back within a short while.
No indication has been given as to what has happened, but on rival Twitter a torrent of comments suggest the problem is worldwide.
The site said: "Sorry, something went wrong. We're working on getting this fixed as soon as we can."
On Twitter the hastag #facebookdown was trending, with users saying it appeared to be down from between 20 and 40 minutes.
The outage was reported in several countries, including New Zealand, Thailand, China, Singapore and India.
Facebook took some time to respond to its users.
“Earlier this morning, we experienced an issue that prevented people from posting to Facebook for a brief period of time. We resolved the issue quickly, and we are now back to 100%. We're sorry for any inconvenience this may have caused,” said a Facebook spokesperson in a statement sent to UK newspaper, The Guardian.
However, across other social media sites public comment was prolific.
Kiwi creative director and radio host, Vaughn Davis, tweeted: “Does anyone mind if I pop around with a picture of what I had for dinner you you can tell me you like it? #facebork”
Other brands took the opportunity to promote themselves on Twitter while Facebook was down. Nestle KitKat tweeted: “Looks like #Facebook is having a BREAK right now. Have a BREAK, too! :) #facebookdown”
Others mocked the significance of the crash of the social media site.
“"Where were you in the Great Facebook Crash of 2014, dad?" "On Twitter son, but I Instagramed about it",” tweeted Australian journalist, Simon Thomsen.
It is not the first time Facebook has crashed. It crashed in June 2013, and also on September 24 2010 the site was out of action for over two and a half hours.
Facebook, the vast, online, global web of family, friends and contacts, is worth US$165 billion (NZ$190b) at last count and with global revenues in the first quarter of the current financial year of US$2.5b.
