Ireland's data protection regulator has launched an investigation into Facebook.
The companyannounced last week that nearly 50 million accounts were breached, and an additional 40 million users were logged out of the platform as a precautionary measure.
The investigation will try to determine whether Facebook was compliant with European regulations.
If it wasn't, Facebook could face $1.6 billion in fines. That's potentially the largest worldwide privacy fine ever imposed, according to Politico.
The investigation comes as the European Union ramps up its data protection policies with its General Data Protection Regulation. The reform vastly changes the way the EU regulates data and adds penalties for privacy violators.
