At roughly 5:10 PM EST we experienced a routing issue that resulted in massive packet loss on our corporate subnet. It took approximately 4 minutes to restore services to 100% while access was available nearly immediately.
This issue would not have affected services as our corporate subnet only hosts OWN services (Shockey Monkey, support portals, monitoring systems).
While most people likely never noticed, this is now an open issue because the BGP connection should have failed over instantly. It was covered in realtime on our Twitter feed.
