The FBI advised everyone to check their computers for malware through a government website to see if they have it. If you have the malware virus on your computer then you'll have to contact your internet provider to get your computer cleaned up and running. The shutdown started at midnight, the hackers planted the virus to several thousands of servers last year.
The FBI found the hackers and pulled the plug thus whoever servers were affected by the hackers virus got disconnected as well. Some people were successful in fixing their computers through the FBI website and some didn't, either they ignored the warning or didn't trust the site. I told a few people to go check their computers and they didn't trust it.
I've check mines and it turned out fine, no virus or anything of that sort, thank goodness! so hopefully they can get this straighten out as soon as possible so thousands of people can get on the internet.
