As everybody knows, yesterday Facebook has the biggest outage ever register in the company.
Just to be clear it has noted that the problem is about DNS and BGP protocol through the network. So, it wasn't attack. It wasn't ransomware. It wasn't hardware problem.
I think that is important to talk about these big problems with IT companies, because is very common hear and see so many fake news about this kind of outage.
Here is a good post of CloudFlare about the problem:
