Coinbase reported “more traffic than we’ve ever encountered,” which meant it needed to “throttle traffic for a few minutes,” Chief Product Officer Surojit Chatterjee said in a tweet.

“We’re back up and ready for you,” Coinbase tweeted separately.

Users on Downdetector had earlier reported problems about 7:20pm ET, shortly after Coinbase aired a Super Bowl advertisement with a QR code that links to a site where new users who sign up for the platform can receive $15 in Bitcoin.
