From medicine to Facebook: The potential of artificial intelligence

Website monitoring group Downdetector said Monday's outage was the largest such failure it had ever seen. While services maybe reconnected, Facebook still has to contend with damaging revelations from an ex-employee.

Shares in Facebook slumped by almost five percent on Wall Street on Monday after its services – including Instagram and WhatsApp – were knocked offline for several hours by a technical problem. Technology shares in general saw a selloff too, including Facebook's rivals like Twitter. Around $6 billion was wiped off the personal fortune of CEO Mark Zuckerberg. Also today, oil prices have jumped after the latest decision by OPEC and its allies not to increase supplies at a faster pace.

Facebook faced a large-scale outage of its dominant social network for seven hours. An IT security expert says "it didn't appear that Facebook thought through this kind of a situation."

We take a look at the jabs, jokes and frenzy over Facebook's seven-hour outage. But first, the French press is widely covering a damning report about paedophilia in the French Catholic church. We also find out about the uncertain, perilous fate of a tanker off the coast of Yemen.

The former Facebook data analyst is testifying before the US Senate following her explosive revelations about the tech giant's knowledge and negligence of its own harmful effects.

Without access to social media, many users felt lost. Their explanations for the technical glitch ranged from wild conspiracy theories to the not-too-far-fetched concern that governments could be blocking the platforms.

In Madagascar, some of the country's highest authorities are accused of bankrolling teams to create fake profiles on Facebook which then share biased or false information for political gain. These fake Facebook accounts stir up controversy, sing the praises of President Andry Rajoelina and criticise journalists and opposition politicians. The communications minister, accused of playing a key role, denies any wrongdoing. Our correspondents report.

What did the planet learn from six hours without Facebook, WhatsApp and Instagram? The glitch triggered by an update on servers went on long enough to remind us how much we put our lives in the hands of a single social media behemoth. It was a chance to realise that we depend on Facebook for everything from private messages to real-time business communications and even payments. Livelihoods depend on it.

In recent days, two former African presidents have been the targets of fake news. In DR Congo, a photo of Joseph Kabila has been circulating with the claim he stood alongside the former head of the rebel group ADF, which has links with the Islamic State group. Another video, meanwhile, purports to show a crowd of supporters of Alpha Condé gathering in Paris... although the man they are shouting in support of is not the ousted Guinean president and it wasn't filmed in Paris at all.

Following revelations by whistleblower Frances Haugen and a global outage, the US company faces renewed scrutiny. It could mark a tipping point and prompt lawmakers to get tough on the tech giant.

Users have been facing issues accessing the social media giant's apps and services for the second time in a week. The company said a configuration change was behind the outage, which is under control.

Facebook is facing a historic crisis. Revelations by former data scientist-turned-whistleblower Frances Haugen have shed light inside the notoriously secretive tech giant. She says Facebook harms children, sparks division and undermines democracy in pursuit of astronomical profits. Her allegations are backed by the leak of tens of thousands of internal documents.
