During the the first quarter of the Big Game, Coinbase aired a tv commercial. The tv commercial consisted of just a QR code changing colors and moving across the screen.
When scanning the QR code, you were immediately taken to a website where new customers could get $15 in free Bitcoin, or current customers could opt in to win $3 million.
Within minutes internet users world wide started to report issues. Download Detector, (see current status) reports that it started shortly after the commercial aired. Current users experienced issues with the app loading.
