Yup.. happened with me too two days ago.. But everything seems fine now. At first I though it's my ISP problem but when everyone had the same problem in my city I understood the root cause must be somewhere else!
As I understand it, half the internet did indeed have to be shut down at least temporarily to save money since there is no bailout plan yet.
If I don't see something I like soon, I'm gonna shut the other half down!!!
