This doesn't seem to be a short hiccup, or even a "short" 1 hour outage. It's been going on for 3.25 hours and counting.
And despite all the articles saying "many users", "some places", "some users" -- can ANYONE get to FB, Instagram, or Whatsapp?
It looks to me like those sites are DOWN. Period. (For now I mean -- not suggesting it's permanent). But I am suggesting the outages are QUITE universal.
